Description: ================================================
        pyDNase - a library for analyzing DNase-seq data
        ================================================
        
        
        Introduction
        ------------
        
        Many people currently analyzing DNase-seq data are using tools designed for ChIP-seq work, but may be inappropriate for DNase-seq data where one is less interested in the overlaps of sequenced fragments, but the site at which the cut occurs (the 5' most end of the aligned sequence fragment).
        
        We have developed `pyDNase` to interface with a sorted and indexed BAM file from a DNase-seq experiment, allowing efficient and easy random access of DNase-seq cut data from any genomic location, e.g.
        
            >>> import pyDNase
            >>> reads = pyDNase.BAMHandler(pyDNase.example_reads())
            >>> reads["chr6,170863500,170863532,+"]
            {'+': array([0,0,0,1,0,0,1,1,2,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,1,1,0,0,0,1]),
             '-': array([0,10,1,0,1,0,4,9,0,1,0,2,1,0,0,0,0,0,3,0,6,3,0,0,0,1,1,1,3,0,3,6])}
        
        Querying the ``BAMHandler`` object returns a dictionary containing numpy arrays with DNase cut counts on the positive reference strand (+), and cuts on the negative reference strand (-). `pyDNase` efficiently caches the cut data queried, so that multiple requests from the same genomic locations do not require repeated lookups from the BAM file (this can be disabled).
        
        `pyDNase` comes with several analysis scripts covering several common use cases of DNase-seq analysis, and also an implementation of the Wellington and Wellington 1D footprinting algorithms.
        
        to install `pyDNase`, ensure NumPy_ is installed, and run::
        
            $ pip install pyDNase
