| Welcome to *hybkit*, a toolkit for analysis of hyb-format chimeric
  (hybrid) RNA sequence data defined with the Hyb software package by |Travis2014|_.
  This genomic data-type is generated from RNA proximity-ligation and ribonomics
  techniques such as Crosslinking, Ligation, and
  Sequencing of Hybrids (CLASH; |Helwak2013|_) and quick CLASH (qCLASH; |Gay2018|_).
| This software is available via Github, at http://www.github.com/RenneLab/hybkit .
| Full project documentation is available at |docs_link|_.

Project components:
    #. hybkit toolkit of command-line utilities for manipulating,
       analyzing, and plotting hyb-format data.
    #. The hybkit python API, an extendable documented codebase
       for creation of custom analyses of hyb-format data.
    #. Integrated analysis of predicted secondary structure (fold) information for
       the API and command-line utilities.
    #. Example analyses for publicly available qCLASH hybrid
       sequence data implemented in each of the command-line scripts and hybkit Python API.

Hybkit Toolkit:
    The hybkit toolkit includes several command-line utilities
    for manipulation of hyb-format data:

        =================================== ===========================================================
        Utility                             Description
        =================================== ===========================================================
        hyb_check                           Parse hyb (and fold) files and check for errors
        hyb_eval                            Evaluate hyb (and fold) records to identify / assign
                                            segment types and miRNAs using custom criteria
        hyb_filter                          Filter hyb (and fold) records to a specific
                                            custom subset
        hyb_analyze                         Perform an energy, type, miRNA, target, or fold analysis
                                            on hyb (and fold) files and plot results
        =================================== ===========================================================

    These scripts are used on the command line with hyb (and associated "vienna" or "CT") files.
    For example, to filter a
    hyb and corresponding vienna file to contain only hybrids with
    a sequence identifier containing the string "kshv":

    Example:

        ::

            $ hyb_filter -i my_hyb_file.hyb -f my_hyb_file.vienna --filter any_seg_contains kshv

    Further detail on the usage of each script is provided in
    the |hybkit Toolkit| section of |docs_link|_.


Hybkit API:
    Hybkit provides a Python3 module with a documented API for interacting with
    records in hyb files and associated vienna or CT files.
    This capability was inspired by the `BioPython Project <https://biopython.org/>`_.
    The primary utility is provided by a class for hyb records (HybRecord), a class
    for fold records (FoldRecord), and file-iterator classes
    (HybFile, ViennaFile, CTFile, HybFoldIter).
    Record attributes can be analyzed, set, and evaluated using included class methods.

    For example, a workflow to print the identifiers of only sequences within a ".hyb" file
    that contain a miRNA can be performed as such:

    .. code-block:: Python

        #!/usr/bin/env python3
        import hybkit
        in_file = '/path/to/my_hyb_file.hyb'

        # Open a hyb file as a HybFile Object:
        with hybkit.HybFile.open(in_file, 'r') as hyb_file:

            # Return each line in a hyb file as a HybRecord object
            for hyb_record in hyb_file:

                # Analyze each record to assign segment types
                hyb_record.eval_types()

                # If the record contains a long noncoding RNA type, print the record identifier.
                if hyb_record.has_prop('any_seg_type_contains', 'lncRNA')
                    print(hyb_record.id)

    Further documentation on the hybkit API can be found in the
    |hybkit API| section of |docs_link|_.

Example Analyses:
    Hybkit provides several example analyses for hyb data using the
    utilities provided in the toolkit. These include:

        ============================= ===========================================================
        Analysis                      Description
        ============================= ===========================================================
        Type/miRNA Analysis           Quantify sequence types and miRNA types in a hyb file
        Target Analysis               Analyze targets of a set of miRNAs from a single
                                      experimental replicate
        Grouped Target Analysis       Analyze and plot targets of a set of miRNAs from
                                      pooled experimental replicates
        Fold Analysis                 Analyze and plot predicted miRNA folding patterns in
                                      miRNA-containing hybrids
        ============================= ===========================================================

    These analyses provide analysis results in both tabular and graph form.
    As an illustration, the example summary analysis includes the return of
    the contained hybrid sequence types as both a csv table and as a pie chart:
