Command line object for bbcontacts [#]_ contact filtering application
https://github.com/soedinglab/bbcontacts
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.
.. [#] Andreani J., Söding J. (2015). bbcontacts: prediction of beta-strand
pairing from direct coupling patterns. Bioinformatics 31(11), 1729-1737.
Examples
--------
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)
bbcontacts
You would typically run the command line with :func:`bbcontacts_cline` or via
the Python subprocess module.
Notes
-----
In order to use bbcontacts, head over to the `GitHub repository
<https://github.com/soedinglab/bbcontacts>`_, download the latest version
and install it using python setup.py install.
