dotpath displays a non-overlapping wordmatch dotplot of two sequences. dotpath is very similar to the program dottup, which looks for places where words (tuples) of a specified length have an exact match in both sequences and draws a diagonal line over the position of those words.

Here is a sample session with dotpath:

% dotpath embl:AF129756 embl:AP000504 -word 20
