POSA (Partial Order Structure Alignment)

A flexible multiple structure alignment approach

Your favorite display method: what's this?

Provide input protein structures (please no more than 20) by one of the three ways below

(1) Provide PDB codes (codes are seperated by spaces; a code is 4-char-ID + 1-char-chain; use _ for no chain)

for example, 1adjA 1hc7A 1qf6A 1atiA

(2) Provide SCOP codes (codes are seperated by spaces; a code is 6-character-ID)

for example, d1ncx__ d2sas__ d1jfja_

(3) Upload a tar/zip file of your PDB structures [help]

Try FATCAT for pairwise flexible structure comparison
