## DESCRIPTION

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

## OPTIONS

### Input section

- **-asequence** *sequence*

  - **-bsequence** *sequence*

  - **-matrixfile** *matrix*

  This is the scoring matrix file used when comparing sequences. By default it is the file 'EBLOSUM62' (for proteins) or the file 'EDNAFULL' (for nucleic sequences). These files are found in the 'data' directory of the EMBOSS installation.

### Additional section

- **-windowsize** *integer*

  Default value: 10

- **-threshold** *integer*

  Default value: 23

### Output section

- **-stretch** *toggle*

  Display a non-proportional graph Default value: N

- **-graph** *graph*

  - **-xygraph** *xygraph*
