there is an option in clustalw program which allows the involvemnet of structure into multiple sequnece alignment. i have a downloaded version of clustalw, which allows profile/structure alignment. plzz try to use that. hope it help Pankaj Kamra Research Scholar National Institute of Immunology New Delhi India -- Open WebMail Project (http://openwebmail.org) ---------- Original Message ----------- From: sangeeta at bioinfo.ernet.in To: rfsouza at cecm.usp.br Sent: Tue, 17 May 2005 14:02:07 +0530 (IST) Subject: Re: [ssml] Structure based multiple sequence alignment > Hi Robson, > *If* you have a large enough set of the 3D structures of the > proteins of your interest, you may try a structural alignment of > those which will give the corresponding sequence alignment also.
