The BIOCCELERATOR at Weizmann Intitute has a Web page for GCG ProfileSearch
and others tools :
http://sgbcd.weizmann.ac.il/Bic/ExecAppl.html

There is also the ISREC Profile Homepage at :
http://ulrec3.unil.ch/profile/profile.html
with informations and references to papers about making profiles from an 
alignment.
