Non-polypeptide molecules are removed from PDB files, which could cause Xwalk to crash. (25/06/11)
A limitation on the maximum number (=150) of SASD calculations for a single protein structure has been placed. This step was necessary to save computer resources on our server as some proteins can have more than 2000 potential vXL. Users still interested in calculating SASD for very large proteins/complexes are advised to download the Xwalk executable. (21/06/11)
News panel added. (21/06/11)
Added warning message for cases where the protein structure holds only one or none cross-linkable amino acid. (15/06/11)
The Application Note for Xwalk got accepted :) (11/06/11)
