Overrides the provided object metadata's bucket value, if any.
destinationObject: Name of the new object. Required when the object
metadata is not otherwise provided. Overrides the object metadata's name
value, if any.

destination object's current generation matches the given value.

maxBytesRewrittenPerCall: The maximum number of bytes that will be
rewritten per Rewrite request. Most callers shouldn't need to specify
this parameter - it is primarily in place to support testing. If
specified the value must be an integral multiple of 1 MiB (1048576).
Also, this only applies to requests where the source and destination
span locations and/or storage classes. Finally, this value must not
change across Rewrite calls else you'll get an error that the rewrite
token is invalid.
object: A Object resource to be passed as the request body.
projection: Set of properties to return. Defaults to noAcl, unless the
object resource specifies the acl property, when it defaults to full.
rewriteToken: Include this field (from the previous Rewrite response) on
each Rewrite request after the first one, until the Rewrite response
'done' flag is true. Calls that provide a rewriteToken can omit all
other request fields, but if included those fields must match the values
provided in the first rewrite request.

Order of methods called matters for dependency reasons.
The locale language is set at the offset and then checked again before

mix of information from more than one locale. This would most likely
happen when using threads where one thread calls a locale-dependent
function while another thread changes the locale while the function in
the other thread is still running. Proper coding would call for
locks to prevent changing the locale while locale-dependent code is
running. The check here is done in case someone does not think about
doing this.
Only other possible issue is if someone changed the timezone and did
not call tz.tzset . That is an issue for the programmer, though,
since changing the timezone is worthless without that call.

Python Script Wrapper for Windows
=================================
setuptools includes wrappers for Python scripts that allows them to be
executed like regular windows programs. There are 2 wrappers, one
for command-line programs, cli.exe, and one for graphical programs,
gui.exe. These programs are almost identical, function pretty much
the same way, and are generated from the same source file. The
wrapper programs are used by copying them to the directory containing
the script they are to wrap and with the same name as the script they
are to wrap.

named out script the way we did. Now we can run out script by running

<p>
This tool will help you perform an upgrade of the PosBox's software.
However the preferred method to upgrade the posbox is to flash the sd-card with
the <a href='http://nightly.openerp.com/trunk/posbox/'>latest image</a>. The upgrade
procedure is explained into to the <a href='/hw_proxy/static/doc/manual.pdf'>PosBox manual</a>
</p>
<p>
To upgrade the posbox, click on the upgrade button. The upgrade will take a few minutes. <b>Do not reboot</b> the PosBox during the upgrade.

Spike train correlation
This modules provides functions to calculate correlations between spike trains.

"""
from __future__ import division
import numpy as np
def corrcoef(binned_sts, binary=False):
'''
Calculate the NxN matrix of pairwise Pearson's correlation coefficients
between all combinations of N binned spike trains.
For each pair of spike trains :math:`(i,j)`, the correlation coefficient :math:`C[i,j]`
is given by the correlation coefficient between the vectors obtained by
binning :math:`i` and :math:`j` at the desired bin size. Let :math:`b_i` and :math:`b_j` denote the
binary vectors and :math:`m_i` and :math:`m_j` their respective averages. Then
.. math::
C[i,j] = <b_i-m_i, b_j-m_j> /
\sqrt{<b_i-m_i, b_i-m_i>*<b_j-m_j,b_j-m_j>}
where <..,.> is the scalar product of two vectors.
For an input of n spike trains, a n x n matrix is returned.
Each entry in the matrix is a real number ranging between -1 (perfectly
anti-correlated spike trains) and +1 (perfectly correlated spike trains).
If binary is True, the binned spike trains are clipped before computing the
correlation coefficients, so that the binned vectors :math:`b_i` and :math:`b_j` are binary.
Parameters
----------
binned_sts : elephant.conversion.BinnedSpikeTrain
A binned spike train containing the spike trains to be evaluated.
binary : bool, optional
If True, two spikes of a particular spike train falling in the same
bin are counted as 1, resulting in binary binned vectors :math:`b_i`. If False,
the binned vectors :math:`b_i` contain the spike counts per bin.
Default: False
Returns
-------
C : ndarrray
The square matrix of correlation coefficients. The element
:math:`C[i,j]=C[j,i]` is the Pearson's correlation coefficient between
binned_sts[i] and binned_sts[j]. If binned_sts contains only one
SpikeTrain, C=1.0.
Examples
--------
Generate two Poisson spike trains
>>> from elephant.spike_train_generation import homogeneous_poisson_process
>>> st1 = homogeneous_poisson_process(rate=10.0*Hz, t_start=0.0*s, t_stop=10.0*s)
>>> st2 = homogeneous_poisson_process(rate=10.0*Hz, t_start=0.0*s, t_stop=10.0*s)
Calculate the correlation matrix.
>>> from elephant.conversion import BinnedSpikeTrain
>>> cc_matrix = corrcoef(BinnedSpikeTrain([st1, st2], binsize=5*ms))
The correlation coefficient between the spike trains is stored in
cc_matrix[0,1] (or cc_matrix[1,0])
Notes
-----
* The spike trains in the binned structure are assumed to all cover the
complete time span of binned_sts [t_start,t_stop).
