This SparseBlock is designed for distributed training with extremely large
input dimension. Both weight and gradient w.r.t. weight are `RowSparseNDArray`.
Note: if `sparse_grad` is set to True, the gradient w.r.t weight will be
sparse. Only a subset of optimizers support sparse gradients, including SGD, AdaGrad
and Adam. By default lazy updates is turned on, which may perform differently
from standard updates. For more details, please check the Optimization API at:

output_dim : int
Dimension of the dense embedding.
dtype : str or np.dtype, default 'float32'

Inputs:
- **data**: (N-1)-D tensor with shape: `(x1, x2, ..., xN-1)`.

Note: Current implementation of SyncBN does not support FP16 training.
For FP16 inference, use standard nn.BatchNorm instead of SyncBN.
Parameters
----------
in_channels : int, default 0
Number of channels (feature maps) in input data. If not specified,
initialization will be deferred to the first time `forward` is called
and `in_channels` will be inferred from the shape of input data.
num_devices : int, default number of visible GPUs
momentum: float, default 0.9
Momentum for the moving average.
epsilon: float, default 1e-5
Small float added to variance to avoid dividing by zero.
center: bool, default True
If True, add offset of `beta` to normalized tensor.
If False, `beta` is ignored.
scale: bool, default True
If True, multiply by `gamma`. If False, `gamma` is not used.
When the next layer is linear (also e.g. `nn.relu`),
this can be disabled since the scaling
will be done by the next layer.
use_global_stats: bool, default False
If True, use global moving statistics instead of local batch-norm. This will force
change batch-norm into a scale shift operator.
If False, use local batch-norm.
beta_initializer: str or `Initializer`, default 'zeros'
Initializer for the beta weight.
gamma_initializer: str or `Initializer`, default 'ones'
Initializer for the gamma weight.
running_mean_initializer: str or `Initializer`, default 'zeros'
Initializer for the running mean.
running_variance_initializer: str or `Initializer`, default 'ones'
Initializer for the running variance.
Inputs:
- **data**: input tensor with arbitrary shape.
Outputs:
- **out**: output tensor with the same shape as `data`.

r"""Pixel-shuffle layer for upsampling in 1 dimension.
Pixel-shuffling is the operation of taking groups of values along
the *channel* dimension and regrouping them into blocks of pixels
along the ``W`` dimension, thereby effectively multiplying that dimension
by a constant factor in size.
For example, a feature map of shape :math:`(fC, W)` is reshaped
into :math:`(C, fW)` by forming little value groups of size :math:`f`
and arranging them in a grid of size :math:`W`.
Parameters
----------
factor : int or 1-tuple of int
Upsampling factor, applied to the ``W`` dimension.
Inputs:
- **data**: Tensor of shape ``(N, f*C, W)``.
Outputs:
- **out**: Tensor of shape ``(N, C, W*f)``.
Examples
--------
>>> pxshuf = PixelShuffle1D(2)

r"""Pixel-shuffle layer for upsampling in 2 dimensions.
Pixel-shuffling is the operation of taking groups of values along
the *channel* dimension and regrouping them into blocks of pixels
along the ``H`` and ``W`` dimensions, thereby effectively multiplying
those dimensions by a constant factor in size.
For example, a feature map of shape :math:`(f^2 C, H, W)` is reshaped
into :math:`(C, fH, fW)` by forming little :math:`f \times f` blocks
of pixels and arranging them in an :math:`H \times W` grid.
Pixel-shuffling together with regular convolution is an alternative,
learnable way of upsampling an image by arbitrary factors. It is reported
to help overcome checkerboard artifacts that are common in upsampling with
transposed convolutions (also called deconvolutions). See the paper
`Real-Time Single Image and Video Super-Resolution Using an Efficient
Sub-Pixel Convolutional Neural Network <https://arxiv.org/abs/1609.05158>`_

Pixel-shuffling (or voxel-shuffling in 3D) is the operation of taking

effectively multiplying those dimensions by a constant factor in size.

"""Filter sample IDs based on subject's coverage of a category.
Given a category that groups samples by subject (subject_category), samples
are filtered by how well a subject covers (i.e. has at least one sample
for) the category states in coverage_category.
Two filtering criteria are provided (min_num_states and required_states).
At least one must be provided. If both are provided, the subject must meet
both criteria to pass the filter (i.e. providing both filters is an AND,
not an OR, operation).
A common use case is to provide a 'time' category for coverage_category and
an 'individual' category for subject_category in order to filter out
individuals from a study that do not have samples for some minimum number
of timepoints (min_num_states) and that do not have samples for certain
timepoints (required_states). For example, this could be the first and last
timepoints in the study.
Returns a set of sample IDs to keep, the number of subjects that were
kept, and a set of the unique category states in coverage_category that
were kept. The set of sample IDs is not guaranteed to be in any specific
order relative to the order of sample IDs or subjects in the mapping file.
Arguments:
mapping_f - metadata mapping file (file-like object)
coverage_category - category to test subjects' coverage (string)
subject_category - category to group samples by subject (string)
min_num_states - minimum number of category states in coverage_category
that a subject must cover (i.e. have at least one sample for) to be
included in results (integer)
required_states - category states in coverage_category that must be
covered by a subject's samples in order to be included in results
(list of strings or items that can be converted to strings)
considered_states - category states that are counted toward the
min_num_states (list of strings or items that can be converted to
strings)
splitter_category - category to split input mapping file on prior to
processing. If not supplied, the mapping file will not be split. If
supplied, a dictionary mapping splitter_category state to results
will be returned instead of the three-element tuple. The supplied
filtering criteria will apply to each split piece of the mapping
file independently (e.g. if an individual passes the filters for
the tongue samples, his/her tongue samples will be included for
the tongue results, even if he/she doesn't pass the filters for the
palm samples)

"""
Create an interface for the modification of a document, based on
the fields that the user has chosen to modify. This avoids having
to redefine a submission page for the modifications, but rely on
the elements already defined for the initial submission i.e. SBI
action (The only page that needs to be built for the modification
is the page letting the user specify a document to modify).
This function should be added at step 1 of your modification
workflow, after the functions that retrieves report number and
record id (Get_Report_Number, Get_Recid). Functions at step 2 are
the one executed upon successful submission of the form.
Create_Modify_Interface expects the following parameters:
* "fieldnameMBI" - the name of a text file in the submission
working directory that contains a list of the names of the
WebSubmit fields to include in the Modification interface.
These field names are separated by"\n" or "+".
Given the list of WebSubmit fields to be included in the
modification interface, the values for each field are retrieved
for the given record (by way of each WebSubmit field being
configured with a MARC Code in the WebSubmit database). An HTML
FORM is then created. This form allows a user to modify certain
field values for a record.
The file referenced by 'fieldnameMBI' is usually generated from a
multiple select form field): users can then select one or several
fields to modify
Note that the function will display WebSubmit Response elements,
but will not be able to set an initial value: this must be done by
the Response element iteself.
Additionally the function creates an internal field named
'Create_Modify_Interface_DONE' on the interface, that can be
retrieved in curdir after the form has been submitted.
This flag is an indicator for the function that displayed values
should not be retrieved from the database, but from the submitted
values (in case the page is reloaded). You can also rely on this
value when building your WebSubmit Response element in order to
retrieve value either from the record, or from the submission
directory.

"""A non-blocking, single-threaded HTTP server.

class except to start a server at the beginning of the process
(and even that is often done indirectly via `tornado.web.Application.listen`).

r"""A non-blocking, single-threaded HTTP server.
A server is defined by a subclass of `.HTTPServerConnectionDelegate`,
or, for backwards compatibility, a callback that takes an
`.HTTPServerRequest` as an argument. The delegate is usually a
`tornado.web.Application`.
`HTTPServer` supports keep-alive connections by default
(automatically for HTTP/1.1, or for HTTP/1.0 when the client
requests ``Connection: keep-alive``).
If ``xheaders`` is ``True``, we support the
``X-Real-Ip``/``X-Forwarded-For`` and
``X-Scheme``/``X-Forwarded-Proto`` headers, which override the
remote IP and URI scheme/protocol for all requests. These headers
are useful when running Tornado behind a reverse proxy or load
balancer. The ``protocol`` argument can also be set to ``https``
if Tornado is run behind an SSL-decoding proxy that does not set one of
the supported ``xheaders``.
To make this server serve SSL traffic, send the ``ssl_options`` keyword
argument with an `ssl.SSLContext` object. For compatibility with older
versions of Python ``ssl_options`` may also be a dictionary of keyword
arguments for the `ssl.wrap_socket` method.::
ssl_ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
ssl_ctx.load_cert_chain(os.path.join(data_dir, "mydomain.crt"),
os.path.join(data_dir, "mydomain.key"))
HTTPServer(applicaton, ssl_options=ssl_ctx)
`HTTPServer` initialization follows one of three patterns (the
initialization methods are defined on `tornado.tcpserver.TCPServer`):
1. `~tornado.tcpserver.TCPServer.listen`: simple single-process::
server = HTTPServer(app)
server.listen(8888)
IOLoop.current().start()
In many cases, `tornado.web.Application.listen` can be used to avoid
the need to explicitly create the `HTTPServer`.
2. `~tornado.tcpserver.TCPServer.bind`/`~tornado.tcpserver.TCPServer.start`:
simple multi-process::
server = HTTPServer(app)
server.bind(8888)
server.start(0) # Forks multiple sub-processes
IOLoop.current().start()
When using this interface, an `.IOLoop` must *not* be passed
to the `HTTPServer` constructor. `~.TCPServer.start` will always start
the server on the default singleton `.IOLoop`.
3. `~tornado.tcpserver.TCPServer.add_sockets`: advanced multi-process::
sockets = tornado.netutil.bind_sockets(8888)
tornado.process.fork_processes(0)
server = HTTPServer(app)
server.add_sockets(sockets)
IOLoop.current().start()
The `~.TCPServer.add_sockets` interface is more complicated,
but it can be used with `tornado.process.fork_processes` to
give you more flexibility in when the fork happens.
`~.TCPServer.add_sockets` can also be used in single-process
servers if you want to create your listening sockets in some
way other than `tornado.netutil.bind_sockets`.
.. versionchanged:: 4.0
Added ``decompress_request``, ``chunk_size``, ``max_header_size``,
``idle_connection_timeout``, ``body_timeout``, ``max_body_size``
arguments. Added support for `.HTTPServerConnectionDelegate`
instances as ``request_callback``.
.. versionchanged:: 4.1
`.HTTPServerConnectionDelegate.start_request` is now called with
two arguments ``(server_conn, request_conn)`` (in accordance with the
documentation) instead of one ``(request_conn)``.
.. versionchanged:: 4.2
`HTTPServer` is now a subclass of `tornado.util.Configurable`.

value is None for symbols and a string for tokens, context is
None or an opaque value used for error reporting (typically a

module: bigip_virtual_server
short_description: Manage LTM virtual servers on a BIG-IP
description:
- Manage LTM virtual servers on a BIG-IP.
version_added: "2.1"
options:
state:
description:
- The virtual server state. If C(absent), delete the virtual server
if it exists. C(present) creates the virtual server and enable it.
If C(enabled), enable the virtual server if it exists. If C(disabled),
create the virtual server if needed, and set state to C(disabled).
default: present
choices:
- present
- absent
- enabled
- disabled
name:
description:
- Virtual server name.
required: True
aliases:
- vs
destination:
description:
- Destination IP of the virtual server.
- Required when C(state) is C(present) and virtual server does not exist.
required: True
aliases:
- address
- ip
source:
description:
- Specifies an IP address or network from which the virtual server accepts traffic.
- The virtual server accepts clients only from one of these IP addresses.
- For this setting to function effectively, specify a value other than 0.0.0.0/0 or ::/0
(that is, any/0, any6/0).
- In order to maximize utility of this setting, specify the most specific address
prefixes covering all customer addresses and no others.
- Specify the IP address in Classless Inter-Domain Routing (CIDR) format; address/prefix,
where the prefix length is in bits. For example, for IPv4, 10.0.0.1/32 or 10.0.0.0/24,
and for IPv6, ffe1::0020/64 or 2001:ed8:77b5:2:10:10:100:42/64.
version_added: 2.5
port:
description:
- Port of the virtual server. Required when C(state) is C(present)
and virtual server does not exist.
- If you do not want to specify a particular port, use the value C(0).
The result is that the virtual server will listen on any port.
profiles:
description:
- List of profiles (HTTP, ClientSSL, ServerSSL, etc) to apply to both sides
of the connection (client-side and server-side).
- If you only want to apply a particular profile to the client-side of
the connection, specify C(client-side) for the profile's C(context).
- If you only want to apply a particular profile to the server-side of
the connection, specify C(server-side) for the profile's C(context).
- If C(context) is not provided, it will default to C(all).
suboptions:
name:
description:
- Name of the profile.
- If this is not specified, then it is assumed that the profile item is
only a name of a profile.
- This must be specified if a context is specified.
required: false
context:
description:
- The side of the connection on which the profile should be applied.
choices:
- all
- server-side
- client-side
default: all
aliases:
- all_profiles
irules:
version_added: "2.2"
description:
- List of rules to be applied in priority order.
- If you want to remove existing iRules, specify a single empty value; C("").
See the documentation for an example.
aliases:
- all_rules
enabled_vlans:
version_added: "2.2"
description:
- List of VLANs to be enabled. When a VLAN named C(all) is used, all
VLANs will be allowed. VLANs can be specified with or without the
leading partition. If the partition is not specified in the VLAN,
then the C(partition) option of this module will be used.
- This parameter is mutually exclusive with the C(disabled_vlans) parameter.
disabled_vlans:
version_added: 2.5
description:
- List of VLANs to be disabled. If the partition is not specified in the VLAN,
then the C(partition) option of this module will be used.
- This parameter is mutually exclusive with the C(enabled_vlans) parameters.
pool:
description:
- Default pool for the virtual server.
- If you want to remove the existing pool, specify an empty value; C("").
See the documentation for an example.
policies:
description:
- Specifies the policies for the virtual server
aliases:
- all_policies
snat:
description:
- Source network address policy.
required: false
choices:
- None
- Automap
- Name of a SNAT pool (eg "/Common/snat_pool_name") to enable SNAT
with the specific pool
default_persistence_profile:
description:
- Default Profile which manages the session persistence.
- If you want to remove the existing default persistence profile, specify an
empty value; C(""). See the documentation for an example.
description:
description:
- Virtual server description.
fallback_persistence_profile:
description:
- Specifies the persistence profile you want the system to use if it
cannot use the specified default persistence profile.
- If you want to remove the existing fallback persistence profile, specify an
empty value; C(""). See the documentation for an example.
version_added: 2.3
partition:
description:
- Device partition to manage resources on.
default: Common
version_added: 2.5
metadata:
description:
- Arbitrary key/value pairs that you can attach to a pool. This is useful in
situations where you might want to annotate a virtual to me managed by Ansible.
- Key names will be stored as strings; this includes names that are numbers.
- Values for all of the keys will be stored as strings; this includes values
that are numbers.
- Data will be persisted, not ephemeral.
version_added: 2.5
notes:
- Requires BIG-IP software version >= 11
- Requires the netaddr Python package on the host. This is as easy as pip
install netaddr.
requirements:
- netaddr

#
# { 'top': { '_a':'1', '_b': 2 }}

# DEFAULT behavior, this becomes:
# <top a="1" b="2"></top> This moves the _names to attributes

Since we are private we get to ignore both 'public' and

FASTA/QUAL format (:mod:`skbio.io.format.fasta`)
================================================
.. currentmodule:: skbio.io.format.fasta
The FASTA file format (``fasta``) stores biological (i.e., nucleotide or
protein) sequences in a simple plain text format that is both human-readable
and easy to parse. The file format was first introduced and used in the FASTA
software package [1]_. Additional descriptions of the file format can be found
in [2]_ and [3]_.
An example of a FASTA-formatted file containing two DNA sequences::
>seq1 db-accession-149855
CGATGTCGATCGATCGATCGATCAG
>seq2 db-accession-34989
CATCGATCGATCGATGCATGCATGCATG
The QUAL file format is an additional format related to FASTA. A FASTA file is
sometimes accompanied by a QUAL file, particuarly when the FASTA file contains
sequences generated on a high-throughput sequencing instrument. QUAL files
store a Phred quality score (nonnegative integer) for each base in a sequence
stored in FASTA format (see [4]_ for more details). scikit-bio supports reading
and writing FASTA (and optionally QUAL) file formats.

.. note:: All readers and writers support an optional QUAL file via the
``qual`` parameter. If one is provided, quality scores will be read/written
in addition to FASTA sequence data.
Format Specification
--------------------
The following sections define the FASTA and QUAL file formats in detail.
FASTA Format
^^^^^^^^^^^^
A FASTA file contains one or more biological sequences. The sequences are
stored sequentially, with a *record* for each sequence (also referred to as a
*FASTA record*). Each *record* consists of a single-line *header* (sometimes
referred to as a *defline*, *label*, *description*, or *comment*) followed by
the sequence data, optionally split over multiple lines.
.. note:: Blank or whitespace-only lines are only allowed at the beginning of
the file, between FASTA records, or at the end of the file. A blank or
whitespace-only line after the header line, within the sequence (for FASTA
files), or within quality scores (for QUAL files) will raise an error.
scikit-bio will ignore leading and trailing whitespace characters on each
line while reading.
.. note:: scikit-bio does not currently support legacy FASTA format (i.e.,
headers/comments denoted with a semicolon). The format supported by
scikit-bio (described below in detail) most closely resembles the
description given in NCBI's BLAST documentation [3]_. See [2]_ for more
details on legacy FASTA format. If you would like legacy FASTA format
support added to scikit-bio, please consider submitting a feature request on
the
`scikit-bio issue tracker <https://github.com/biocore/scikit-bio/issues>`_
(pull requests are also welcome!).
Sequence Header
~~~~~~~~~~~~~~~
Each sequence header consists of a single line beginning with a greater-than
(``>``) symbol. Immediately following this is a sequence identifier (ID) and
description separated by one or more whitespace characters. The sequence ID and
description are stored in the sequence `metadata` attribute, under the `'id'`
and `'description'` keys, repectively. Both are optional. Each will be
represented as the empty string (``''``) in `metadata` if it is not present
in the header.
A sequence ID consists of a single *word*: all characters after the greater-
than symbol and before the first whitespace character (if any) are taken as the
sequence ID. Unique sequence IDs are not strictly enforced by the FASTA format
itself. A single standardized ID format is similarly not enforced by the FASTA
format, though it is often common to use a unique library accession number for
a sequence ID (e.g., NCBI's FASTA defline format [5]_).
.. note:: scikit-bio will enforce sequence ID uniqueness depending on the type
of object that the FASTA file is read into. For example, reading a FASTA
file as a generator of ``Sequence`` objects will not enforce
unique IDs since it simply yields each sequence it finds in the FASTA file.
However, if the FASTA file is read into a ``SequenceCollection`` object, ID
uniqueness will be enforced because that is a requirement of a
``SequenceCollection``.
If a description is present, it is taken as the remaining characters that
follow the sequence ID and initial whitespace(s). The description is considered
additional information about the sequence (e.g., comments about the source of
the sequence or the molecule that it encodes).
For example, consider the following header::
>seq1 db-accession-149855
``seq1`` is the sequence ID and ``db-accession-149855`` is the sequence
description.
.. note:: scikit-bio's readers will remove all leading and trailing whitespace
from the description. If a header line begins with whitespace following the
``>``, the ID is assumed to be missing and the remainder of the line is
taken as the description.
Sequence Data
~~~~~~~~~~~~~
Biological sequence data follows the header, and can be split over multiple
lines. The sequence data (i.e., nucleotides or amino acids) are stored using
the standard IUPAC lexicon (single-letter codes).
.. note:: scikit-bio supports both upper and lower case characters.
This functionality depends on the type of object the data is
being read into. For ``Sequence``
objects, sciki-bio doesn't care about the case. However, for other object
types, such as :class:`skbio.sequence.DNA`, :class:`skbio.sequence.RNA`,
and :class:`skbio.sequence.Protein`, the `lowercase` parameter
must be used to control case functionality. Refer to the documentation for
the constructors for details.
.. note:: Both ``-`` and ``.`` are supported as gap characters. See
:mod:`skbio.sequence` for more details on how scikit-bio interprets
sequence data in its in-memory objects.
Validation is performed for all scikit-bio objects which support it. This
consists of all objects which enforce usage of IUPAC characters. If any
invalid IUPAC characters are found in the sequence while reading from the
FASTA file, an exception is raised.
QUAL Format
^^^^^^^^^^^
A QUAL file contains quality scores for one or more biological sequences stored
in a corresponding FASTA file. QUAL format is very similar to FASTA format: it
stores records sequentially, with each record beginning with a header line
containing a sequence ID and description. The same rules apply to QUAL headers
as FASTA headers (see the above sections for details). scikit-bio processes
FASTA and QUAL headers in exactly the same way.
Quality scores are automatically stored in the object's `positional_metadata`
attribute, under the `'quality'` column.
Instead of storing biological sequence data in each record, a QUAL file stores
a Phred quality score for each base in the corresponding sequence. Quality
scores are represented as nonnegative integers separated by whitespace
(typically a single space or newline), and can span multiple lines.
.. note:: When reading FASTA and QUAL files, scikit-bio requires records to be
in the same order in both files (i.e., each FASTA and QUAL record must have
the same ID and description after being parsed). In addition to having the
same order, the number of FASTA records must match the number of QUAL
records (i.e., missing or additonal records are not allowed). scikit-bio
also requires that the number of quality scores match the number of bases in
the corresponding sequence.
When writing FASTA and QUAL files, scikit-bio will maintain the same
ordering of records in both files (i.e., using the same ID and description
in both records) to support future reading.
Format Parameters
-----------------
The following parameters are available to change how FASTA/QUAL files are read
or written in scikit-bio.
QUAL File Parameter (Readers and Writers)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The ``qual`` parameter is available to all FASTA format readers and writers. It
can be any file-like type supported by scikit-bio's I/O registry (e.g., file
handle, file path, etc.). If ``qual`` is provided when reading, quality scores
will be included in each in-memory ``Sequence`` object, in addition
to sequence data stored in the FASTA file. When writing, quality scores will be
written in QUAL format in addition to the sequence data being written in FASTA
format.
Reader-specific Parameters
^^^^^^^^^^^^^^^^^^^^^^^^^^
The available reader parameters differ depending on which reader is used.
Generator, SequenceCollection, and Alignment Reader Parameters
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The ``constructor`` parameter can be used with the ``Sequence``
generator, ``SequenceCollection``, and ``Alignment`` FASTA readers.
``constructor`` specifies the in-memory type of each sequence that is parsed,
and defaults to ``Sequence``. ``constructor`` should be a subclass of
``Sequence``. For example, if you know that the FASTA file you're
reading contains protein sequences, you would pass
``constructor=Protein`` to the reader call.
.. note:: The FASTA sniffer will not attempt to guess the ``constructor``
parameter, so it will always default to ``Sequence`` if another
type is not provided to the reader.
Sequence Reader Parameters
~~~~~~~~~~~~~~~~~~~~~~~~~~
The ``seq_num`` parameter can be used with the ``Sequence``,
``DNA``, ``RNA``, and ``Protein`` FASTA readers. ``seq_num`` specifies which
sequence to read from the FASTA file (and optional QUAL file), and defaults to
1 (i.e., such that the first sequence is read). For example, to read the 50th
sequence from a FASTA file, you would pass ``seq_num=50`` to the reader call.
Writer-specific Parameters
^^^^^^^^^^^^^^^^^^^^^^^^^^
The following parameters are available to all FASTA format writers:
- ``id_whitespace_replacement``: string to replace **each** whitespace
character in a sequence ID. This parameter is useful for cases where an
in-memory sequence ID contains whitespace, which would result in an on-disk
representation that would not be read back into memory as the same ID (since
IDs in FASTA format cannot contain whitespace). Defaults to ``_``. If
``None``, no whitespace replacement is performed and IDs are written as they
are stored in memory (this has the potential to create an invalid
FASTA-formatted file; see note below). This parameter also applies to a QUAL
file if one is provided.
- ``description_newline_replacement``: string to replace **each** newline
character in a sequence description. Since a FASTA header must be a single
line, newlines are not allowed in sequence descriptions and must be replaced
in order to write a valid FASTA file. Defaults to a single space. If
``None``, no newline replacement is performed and descriptions are written as
they are stored in memory (this has the potential to create an invalid
FASTA-formatted file; see note below). This parameter also applies to a QUAL
file if one is provided.
- ``max_width``: integer specifying the maximum line width (i.e., number of
characters) for sequence data and/or quality scores. If a sequence or its
quality scores are longer than ``max_width``, it will be split across
multiple lines, each with a maximum width of ``max_width``. Note that there
are some caveats when splitting quality scores. A single quality score will
*never* be split across multiple lines, otherwise it would become two
different quality scores when read again. Thus, splitting only occurs
*between* quality scores. This makes it possible to have a single long
quality score written on its own line that exceeds ``max_width``. For
example, the quality score ``12345`` would not be split across multiple lines
even if ``max_width=3``. Thus, a 5-character line would be written. Default
behavior is to not split sequence data or quality scores across multiple
lines.
- ``lowercase``: String or boolean array. If a string, it is treated as a key
into the positional metadata of the object. If a boolean array, it
indicates characters to write in lowercase. Characters in the sequence
corresponding to `True` values will be written in lowercase. The boolean
array must be the same length as the sequence.
.. note:: The FASTA format writers will have noticeably better runtime
performance if ``id_whitespace_replacement`` and/or
``description_newline_replacement`` are set to ``None`` so that whitespace
replacement is not performed during writing. However, this can potentially
create invalid FASTA files, especially if there are newline characters in
the IDs or descriptions. For IDs with whitespace, this can also affect how
the IDs are read into memory in a subsequent read operation. For example, if
an in-memory sequence ID is ``'seq 1'`` and
``id_whitespace_replacement=None``, reading the FASTA file back into memory
would result in an ID of ``'seq'``, and ``'1'`` would be part of the
sequence description.
Examples
--------
Reading and Writing FASTA Files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Suppose we have the following FASTA file with five equal-length sequences
(example modified from [6]_)::
>seq1 Turkey
AAGCTNGGGCATTTCAGGGTGAGCCCGGGCAATACAGGGTAT
>seq2 Salmo gair
AAGCCTTGGCAGTGCAGGGTGAGCCGTGG
CCGGGCACGGTAT
>seq3 H. Sapiens

>seq4 Chimp
AAACCCTTGCCG
TTACGCTTAAAC
CGAGGCCGGGAC
ACTCAT
>seq5 Gorilla
AAACCCTTGCCGGTACGCTTAAACCATTGCCGGTACGCTTAA

*(c) Copyright 1986-2008 by The University of Washington. Written by Joseph
Felsenstein. Permission is granted to copy this document provided that no
fee is charged for it and that this copyright notice is not removed.*
Note that the sequences are not required to be of equal length in order for the
file to be a valid FASTA file (this depends on the object that you're reading
the file into). Also note that some of the sequences occur on a single line,
while others are split across multiple lines.
Let's define this file in-memory as a ``StringIO``, though this could be a real
file path, file handle, or anything that's supported by scikit-bio's I/O
registry in practice:
>>> fl = [u">seq1 Turkey\\n",
... u"AAGCTNGGGCATTTCAGGGTGAGCCCGGGCAATACAGGGTAT\\n",
... u">seq2 Salmo gair\\n",
... u"AAGCCTTGGCAGTGCAGGGTGAGCCGTGG\\n",
... u"CCGGGCACGGTAT\\n",
... u">seq3 H. Sapiens\\n",
... u"ACCGGTTGGCCGTTCAGGGTACAGGTTGGCCGTTCAGGGTAA\\n",
... u">seq4 Chimp\\n",
... u"AAACCCTTGCCG\\n",
... u"TTACGCTTAAAC\\n",
... u"CGAGGCCGGGAC\\n",
... u"ACTCAT\\n",
... u">seq5 Gorilla\\n",
... u"AAACCCTTGCCGGTACGCTTAAACCATTGCCGGTACGCTTAA\\n"]
Let's read the FASTA file into a ``SequenceCollection``:
>>> from skbio import SequenceCollection
>>> sc = SequenceCollection.read(fl)
>>> sc.sequence_lengths()
[42, 42, 42, 42, 42]
>>> sc.ids()
[u'seq1', u'seq2', u'seq3', u'seq4', u'seq5']
We see that all 5 sequences have 42 characters, and that each of the sequence
IDs were successfully read into memory.
Since these sequences are of equal length (presumably because they've been
aligned), let's load the FASTA file into an ``Alignment`` object, which is a
more appropriate data structure:
>>> from skbio import Alignment
>>> aln = Alignment.read(fl)
>>> aln.sequence_length()
42
Note that we were able to read the FASTA file into two different data
structures (``SequenceCollection`` and ``Alignment``) using the exact same
``read`` method call (and underlying reading/parsing logic). Also note that we
didn't specify a file format in the ``read`` call. The FASTA sniffer detected
the correct file format for us!
Let's inspect the type of sequences stored in the ``Alignment``:
>>> aln[0]
Sequence
------------------------------------------------
Metadata:
u'description': u'Turkey'
u'id': u'seq1'
Stats:
length: 42
------------------------------------------------
0 AAGCTNGGGC ATTTCAGGGT GAGCCCGGGC AATACAGGGT AT
By default, sequences are loaded as ``Sequence`` objects. We can
change the type of sequence via the ``constructor`` parameter:
>>> from skbio import DNA
>>> aln = Alignment.read(fl, constructor=DNA)
>>> aln[0] # doctest: +NORMALIZE_WHITESPACE
DNA

We now have an ``Alignment`` of ``DNA`` objects instead of
``Sequence`` objects.
To write the alignment in FASTA format:
>>> from io import StringIO
>>> with StringIO() as fh:
... print(aln.write(fh).getvalue())
>seq1 Turkey
AAGCTNGGGCATTTCAGGGTGAGCCCGGGCAATACAGGGTAT

AAACCCTTGCCGGTACGCTTAAACCATTGCCGGTACGCTTAA
<BLANKLINE>
Both ``SequenceCollection`` and ``Alignment`` load all of the sequences from
the FASTA file into memory at once. If the FASTA file is large (which is often
the case), this may be infeasible if you don't have enough memory. To work
around this issue, you can stream the sequences using scikit-bio's
generator-based FASTA reader and writer. The generator-based reader yields
``Sequence`` objects (or subclasses if ``constructor`` is supplied)
one at a time, instead of loading all sequences into memory. For example, let's
use the generator-based reader to process a single sequence at a time in a
``for`` loop:
>>> import skbio.io
>>> for seq in skbio.io.read(fl, format='fasta'):
... seq
... print('')

Reading and Writing FASTA/QUAL Files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In addition to reading and writing standalone FASTA files, scikit-bio also
supports reading and writing FASTA and QUAL files together. Suppose we have the
following FASTA file::
>seq1 db-accession-149855
CGATGTC
>seq2 db-accession-34989
CATCG
Also suppose we have the following QUAL file::
>seq1 db-accession-149855
40 39 39 4
50 1 100
>seq2 db-accession-34989
3 3 10 42 80
>>> fasta_fl = [
... u">seq1 db-accession-149855\\n",
... u"CGATGTC\\n",
... u">seq2 db-accession-34989\\n",
... u"CATCG\\n"]
>>> qual_fl = [
... u">seq1 db-accession-149855\\n",
... u"40 39 39 4\\n",
... u"50 1 100\\n",
... u">seq2 db-accession-34989\\n",
... u"3 3 10 42 80\\n"]
To read in a single ``Sequence`` at a time, we can use the
generator-based reader as we did above, providing both FASTA and QUAL files:
>>> for seq in skbio.io.read(fasta_fl, qual=qual_fl, format='fasta'):
... seq
... print('')
Sequence
------------------------------------------
Metadata:
u'description': u'db-accession-149855'
u'id': u'seq1'

u'quality': <dtype: uint8>

u'id': u'seq2'
Positional metadata:
u'quality': <dtype: uint8>

-----------------------------------------
0 CATCG
<BLANKLINE>
Note that the sequence objects have quality scores stored as positional
metadata since we provided a QUAL file. The other FASTA readers operate in a
similar manner.
Now let's load the sequences and their quality scores into a
``SequenceCollection``:
>>> sc = SequenceCollection.read(fasta_fl, qual=qual_fl)
>>> sc
<SequenceCollection: n=2; mean +/- std length=6.00 +/- 1.00>
To write the sequence data and quality scores in the ``SequenceCollection`` to
FASTA and QUAL files, respectively, we run:
>>> new_fasta_fh = StringIO()
>>> new_qual_fh = StringIO()
>>> _ = sc.write(new_fasta_fh, qual=new_qual_fh)
>>> print(new_fasta_fh.getvalue())
>seq1 db-accession-149855
CGATGTC
>seq2 db-accession-34989
CATCG
<BLANKLINE>
>>> print(new_qual_fh.getvalue())
>seq1 db-accession-149855
40 39 39 4 50 1 100
>seq2 db-accession-34989
3 3 10 42 80
<BLANKLINE>
>>> new_fasta_fh.close()
>>> new_qual_fh.close()

"""This class can be used to conveniently create a WSGI environment
for testing purposes. It can be used to quickly create WSGI environments
or request objects from arbitrary data.
The signature of this class is also used in some other places as of
Werkzeug 0.5 (:func:`create_environ`, :meth:`BaseResponse.from_values`,
:meth:`Client.open`). Because of this most of the functionality is
available through the constructor alone.
Files and regular form data can be manipulated independently of each
other with the :attr:`form` and :attr:`files` attributes, but are
passed with the same argument to the constructor: `data`.
`data` can be any of these values:
- a `str`: If it's a string it is converted into a :attr:`input_stream`,
the :attr:`content_length` is set and you have to provide a
:attr:`content_type`.
- a `dict`: If it's a dict the keys have to be strings and the values
any of the following objects:
- a :class:`file`-like object. These are converted into
:class:`FileStorage` objects automatically.
- a tuple. The :meth:`~FileMultiDict.add_file` method is called
with the tuple items as positional arguments.
.. versionadded:: 0.6
`path` and `base_url` can now be unicode strings that are encoded using
the :func:`iri_to_uri` function.
:param path: the path of the request. In the WSGI environment this will
end up as `PATH_INFO`. If the `query_string` is not defined
and there is a question mark in the `path` everything after
it is used as query string.
:param base_url: the base URL is a URL that is used to extract the WSGI
URL scheme, host (server name + server port) and the
script root (`SCRIPT_NAME`).
:param query_string: an optional string or dict with URL parameters.
:param method: the HTTP method to use, defaults to `GET`.
:param input_stream: an optional input stream. Do not specify this and
`data`. As soon as an input stream is set you can't
modify :attr:`args` and :attr:`files` unless you
set the :attr:`input_stream` to `None` again.
:param content_type: The content type for the request. As of 0.5 you
don't have to provide this when specifying files
and form data via `data`.
:param content_length: The content length for the request. You don't
have to specify this when providing data via
`data`.
:param errors_stream: an optional error stream that is used for
`wsgi.errors`. Defaults to :data:`stderr`.
:param multithread: controls `wsgi.multithread`. Defaults to `False`.
:param multiprocess: controls `wsgi.multiprocess`. Defaults to `False`.
:param run_once: controls `wsgi.run_once`. Defaults to `False`.
:param headers: an optional list or :class:`Headers` object of headers.
:param data: a string or dict of form data. See explanation above.
:param environ_base: an optional dict of environment defaults.
:param environ_overrides: an optional dict of environment overrides.
