       distmat - Create a distance matrix from a multiple sequence alignment


       distmat -sequence seqset -nucmethod list -protmethod list -ambiguous boolean
               -gapweight float -position integer -calculatea boolean -parametera float
               -outfile outfile

       distmat -help


       distmat is a command line program from EMBOSS (“the European Molecular Biology Open
       Software Suite”). It is part of the "Phylogeny:Molecular sequence" command group(s).


   Input section
       -sequence seqset
           File containing a sequence alignment.

   Required section
       -nucmethod list
           Multiple substitution correction methods for nucleotides.

       -protmethod list
           Multiple substitution correction methods for proteins.

   Additional section
       -ambiguous boolean
           Option to use the ambiguous codes in the calculation of the Jukes-Cantor method or if
           the sequences are proteins. Default value: N

       -gapweight float
           Option to weight gaps in the uncorrected (nucleotide) and Jukes-Cantor distance
           methods. Default value: 0.

       -position integer
           Choose base positions to analyse in each codon i.e. 123 (all bases), 12 (the first two
           bases), 1, 2, or 3 individual bases. Default value: 123

       -calculatea boolean
           This will force the calculation of parameter 'a' in the Jin-Nei Gamma distance
           calculation, otherwise the default is 1.0 (see -parametera option). Default value: N

       -parametera float
           User defined parameter 'a' to be use in the Jin-Nei Gamma distance calculation. The
           suggested value to be used is 1.0 (Jin et al.) and this is the default. Default value:

   Output section
       -outfile outfile
