Someone recently posted a message regarding Kay Hofmann's prograph
program. I pulled it up and it is great for determining anything
about a protein sequence which depends on the properties of
individual amino acids. It is very user friendly, flexible, and
fun to use. It requires a graphics board, EGA, VGA or hercules,
and mouse. I first tried it in the office and ran home and bought
a mouse for my home computer so I could run it there.
This program together with Don Roufa's Seqaid program, also
available from the embl file server make for a powerful software
package for not a lot of money (free). When you combine these with
the search and retrieval service now offered by the International
Nucleotide Sequence databases (GenBank/EMBL/DDBJ) and PIR
International you have a powerful combination.
