       diffseq - Compare and report features of two similar sequences

       diffseq -help


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


   Input section
       -asequence sequence

       -bsequence sequence

   Required section
       -wordsize integer
           The similar regions between the two sequences are found by creating a hash table of
           'wordsize'd subsequences. 10 is a reasonable default. Making this value larger (20?)
           may speed up the program slightly, but will mean that any two differences within
           'wordsize' of each other will be grouped as a single region of difference. This value
           may be made smaller (4?) to improve the resolution of nearby differences, but the
           program will go much slower. Default value: 10

   Additional section
       -globaldifferences boolean
           Normally this program will find regions of identity that are the length of the
           specified word-size or greater and will then report the regions of difference between
           these matching regions. This works well and is what most people want if they are
           working with long overlapping nucleic acid sequences. You are usually not interested
           in the non-overlapping ends of these sequences. If you have protein sequences or short
           RNA sequences however, you will be interested in differences at the very ends . It
           this option is set to be true then the differences at the ends will also be reported.
           Default value: N

   Output section
       -outfile report

       -aoutfeat featout
           File for output of first sequence's features Default value: $(

       -boutfeat featout
           File for output of second sequence's features Default value: $(
