Command line object for bbcontacts [1] contact filtering application

The bbcontacts program is a Python program predicting residue-level contacts between beta-strands by detecting patterns in matrices of predicted couplings. bbcontacts can make use of a secondary structure assignment or a secondary structure prediction.

To filter a contact map using a Multiple Sequence Alignment in CCMpred format, use:

>>> from conkit.applications import BbcontactsCommandline
>>> bbcontacts_cline = BbcontactsCommandline(
...     matfile='test.mat', diversity_score=0.482, prefix='test'
... )
>>> print(bbcontacts_cline)

You would typically run the command line with bbcontacts_cline() or via the subprocess module.
