# csb-bfite(1)

models non-rigid displacements in protein ensembles with outlier-tolerant probability distributions

## NAME

csb-bfite - models non-rigid displacements in protein ensembles with outlier-tolerant probability distributions

## DESCRIPTION

usage: csb-bfite \[-h\] \[-c CHAIN\] \[-s {student,k}\] \[-a ALIGNMENT\] \[-o OUTFILE\]

-

  \[-n NITER\] pdb

Python application for robust structure superposition of an ensemble of structures. bfite models non-rigid displacements in protein ensembles with outlier-tolerant probability distributions.

### positional arguments:

- pdb

  full path to the ensemble

### optional arguments:

- **-h**, **--help**

  show this help message and exit

- **-c** CHAIN, **--chain** CHAIN

  Chain (default=A)

- **-s** {student,k}, **--scalemixture** {student,k}

  Scale mixture distribution (default=student)

- **-a** ALIGNMENT, **--alignment** ALIGNMENT

  Alignment in fasta format defining equivalent positions Assumes that chain1 is the first sequence of the alignment and chain2 the second sequence

- **-o** OUTFILE, **--outfile** OUTFILE

  file to which the rotated second structure will be written (default=bfit.pdb)

- **-n** NITER, **--niter** NITER

  Number of optimization steps (default=200)
