Dear Chimera people, Many thanks to all Chimera contributors. Please may I propose an addition to allow users to access our CATH domains in the same way that they can currently access SCOP domains ( https://www.cgl.ucsf.edu/chimera/docs/UsersGuide/scop.html )? PDBs for CATH domains can be loaded from URI's of the form: http://data.cathdb.info/latest_release/pdb/1cukA01 For information, CATH domain IDs contain 7 digits: - 1-4 : (eg 1cuk ) : PDB code - 5 : (eg A ) : chain code - 6-7 : (eg 01 ) : 2-digit domain number ( '00' for whole chain domains ) We here at CATH would be very happy to provide any other information required to implement this. Many thanks for your help. Kind regards, Tony Dr Tony Lewis Orengo Group UCL
