On a Mac you can delete columns in Microsoft word, by holding
down the OPTION key as you select text.  I suspect that this
will not be convientient with PHYLIP files unless you
can convince Word to us a page width that is very wide.

I have access to a program which strips any site in an alignmnet
which contains a gap in any of the sequences.  It is called GapStrip.
I will check into it on Monday and see where we got it.
It is a UNIX program.

MASE (multiple alignment sequence editor) is shareware or freeware
and does a good job, but not automatically.  I can also look up
where to get this, or you could search the WWW for it.

: Many thanks
