NAME

       hmm_tweak - Alter transition probabilities in an HMM definition file.

DESCRIPTION

       Alter  transition  probabilities  in  an  HMM definition file.  After specified operations are performed,
       transition probabilities are renormalized and the adjusted file is written to standard out.  This program
       may be used multiple times in a pipe.

USAGE

       hmm_tweak [OPTIONS] <file.hmm> <cmap.cm>

OPTIONS

       -f <cats>
              Operate  on  transitions *from* states corresponding to the specified category names (default all)
              -t <cats> Operate on transitions  *to*  states  corresponding  to  the  specified  category  names
              (default all) -m <fact> Multiply transition probabilities by the specified factor.

       -a <const> Add the specified constant to transition probabilities.  -e <val> Set transition probabilities
              equal to the specified value.

       -i <icats> Assume a phylo-HMM indel model for states corresponding to

              the specified category names.  -u <tree> (Required with -i) Assume given tree topology (.nh file).
              -F  <gps>  (For  use  with  -i)  Operate  on  transitions  from  states corresp.  to the specified
              gap-pattern numbers (ANDed with -f).

       -T <gps>
              (For use with -i) Operate on transitions to states corresp.  to the specified gap-pattern  numbers
              (ANDed  with  -t).   -z  Equalize  transition  probabilities.   Set  all  transition probabilities
              indicated by -f/-t/-F/-T to their overall average value.  Options -m and/or  -a  can  be  used  to
              adjust  this  average  value.   -R Restrict to successive transitions within a category range.  -y
              Like -z, except compute separate averages for five  classes  of  transitions,  based  on  the  gap
              patterns  of  the states involved: between null gap patterns, between equal non-null gap patterns,
              from null to non-null gap patterns, from non-null to null gap patterns, and  all  others.   Useful
              with  the indel model when training data is sparse (e.g., for splice-site states).  Options -m and
              -a will be applied to transitions of the 3rd and 5th classes described.

       -h     Print this help message.
