Jeremy,
Under MS-DOS, you could use my editor Esee3 which has a delete
column function as well as the ability to output data files in
the Phylip format.
Esee3 (Eyeball SEquence Editor, version 3.0) is
available via anonymous ftp/gopher at:
trog.mbb.sfu.ca.
Look for the file esee3zip.exe in the directory pub/esee.
Alternatively, you could point your web-browser at:
gopher://trog.mbb.sfu.ca:70/11/Software/esee
or
http://elmo.niddk.nih.gov/Esee3/esee3zip.exe
For more information on Esee3 consult the archive mentioned above
or connect to my server at:
http://elmo.niddk.nih.gov/Esee3/Readme.html
or
http://elmo.niddk.nih.gov/Esee3/eseeread.html
Note: The "elmo" server is usually only available during working hours,
US Eastern Standard Time.
