NAME
       probcons - align multiple protein sequences and print to standard output


SYNOPSIS
       probcons [OPTION] [MFAFILE] [MFAFILE]


DESCRIPTION
       probcons is a tool for generating multiple alignments of protein sequences. Using a combination of
       probabilistic modeling and consistency-based alignment techniques, PROBCONS has achieved the highest
       accuracies of all alignment methods to date. On the BAliBASE benchmark alignment database, alignments
       produced by PROBCONS show statistically significant improvement over current programs, containing an
       average of 7% more correctly aligned columns than those of T-Coffee, 11% more correctly aligned columns
       than those of CLUSTAL W, and 14% more correctly aligned columns than those of DIALIGN.

       probcons aligns sequences provided in MFA format. This format consists of multiple sequences. Each
       sequence in MFA format begins with a single-line description, followed by lines of sequence data. The
       description line is distinguished from the sequence data by a greater-than (“>”) symbol in the first
       column.


OPTIONS
       -clustalw
           use CLUSTALW output format instead of MFA

       -c --consistency REPS
           use 0 <= REPS <= 5 (default: 2) passes of consistency transformation

       -ir --iterative-refinement REPS
           use 0 <= REPS <=1000 (default: 100) passes of iterative-refinement

       -pre --pre-training REPS
           use 0 <= REPS <= 20 (default: 0) rounds of pretraining

       -pairs
           generate all-pairs pairwise alignments

       -viterbi
           use Viterbi algorithm to generate all pairs (automatically enables -pairs)

       -v --verbose
           Report progress while aligning (default: off)

       -annot FILENAME
           write annotation for multiple alignment to FILENAME

       -t --train FILENAME
           compute EM transition probabilities, store in FILENAME (default: no training)

       -e --emissions
           also reestimate emission probabilities (default: off)

       -p --paramfile FILENAME
           read parameters from FILENAME (default: )

       -a --alignment-order
           print sequences in alignment order rather than input order (default: off)

       •   You can find more information in the manual of ProbCons, which is located in
           /usr/share/doc/probcons/manual.pdf in Debian systems.

       •   An experimental version of ProbCons compiled with parameters estimated via unsupervised training on
           BRAliBASE, probcons-RNA(1), is also distributed in the ProbCons Debian package.

       •    pc-makegnufile(1), pc-compare(1), pc-project(1), which are distributed separately in the
           probcons-extra package.
