Function

   Finds regions of identity (exact matches) of two sequences

Description

   wordmatch finds all regions of identity (exact matches) of a specified
   minimum size of two input sequences. These regions are reported in a
   standard EMBOSS alignment file and in standard EMBOSS sequence feature
   files.

Usage

   Here is a sample session with wordmatch


% wordmatch tsw:hba_human tsw:hbb_human
Finds regions of identity (exact matches) of two sequences
Word size [4]:
Output alignment [hba_human.wordmatch]:
Features output [hba_human.gff]:
Second features output [HBB_HUMAN.gff]:

Output file format

   The output is a standard EMBOSS alignment file.

   The results can be output in one of several styles by using the
   command-line qualifier -aformat xxx, where 'xxx' is replaced by the
   name of the required format. Some of the alignment formats can cope
   with an unlimited number of sequences, while others are only for pairs
   of sequences.

   The available multiple alignment format names are: unknown, multiple,
   simple, fasta, msf, trace, srs

   The available pairwise alignment format names are: pair, markx0,
   markx1, markx2, markx3, markx10, srspair, score

   See: http://emboss.sf.net/docs/themes/AlignFormats.html for further
   information on alignment formats.

   The normal 'report' header is output. It contains the details of the
   program run and the input sequences.

   The data lines consist of five columns separated by spaces or TAB
   characters. Each line contains the information on one identical region.
   The first column is the length of the match. The second column is the
   name of the first sequence. The third column is the start and end
   position of the match. The next two columns are the name and positions
   of the second sequence.

Data files

   None.

Notes

   wormatch will only report identical regions that are at least as long
   as the specified wordsize.

References

   None.

Warnings

   None.

Diagnostic Error Messages

   None.

Exit status

   0 if successful.

Known bugs
