A few years ago (during my pre-perl years) I wrote some unix shell scripts to
call bestfit and/or gap, so I know it's possible to call GCG programs from
the command line. What have you tried?
That said, I agree with Brian: EMBOSS has a lot of great tools, so you may
want to look into installing it (the two alignment programs you'd probably be
most interested in are 'needle' and 'water'). The one catch is that it
requires a *nix OS, so if you're running Windows you'll need to look into
Finally, take a look at the pSW module in Bio::Tools, if you want to call a
local alignment algorithm from perl. There isn't a global alignment module
yet, AFAIK, but if you need one you could try to tweek pSW. Alternatively, I
wrote a needleman-wunsch module that I would be happy to share, but it's far
from optimized and (since I'm still quite the beginner) probably fairly ugly
