       probcons - align multiple protein sequences and print to standard


       probcons [OPTION] [MFAFILE] [MFAFILE]


       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.


           use CLUSTALW output format instead of MFA

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

       -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

           generate all-pairs pairwise alignments

           use Viterbi algorithm to generate all pairs (automatically enables

       -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

       -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)

           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.

           distributed separately in the probcons-extra package.
