Firstly, remember that GCG can convert other sequence formats. You must
already have these sequences in some format, so for example if they are
in one file in PIR format you could try frompir to create GCG format
then use *.seq or whatever to read them in.
You will also probably have to change the parameters in the PileUp code
to allow so many sequences - for example make a new version (under another
name) that allows more sequences but limits their length.
Oh yes, and don't use WPI. Just putting *.seq on the command line is
*so* much easier.
But having done that, how do you plan to edit the alignment you get?
You could also try other alignment programs, CLUSTALW for example.
If you have an account on the Belgian EMBnet node, I'm sure they can help
you too.
