-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear all, I have small suggestion to make that I would find helpful if implemented in chimera: I think it would be great if the "biological assembly" could be fetched by ID from the File menu, just as it goes now for the pdb coordinates file from the RCSB site. Such assemblies are kept at the PQS database at the EBI (Cambridge). The links there follow this syntax: http://pqs.ebi.ac.uk/pqs-doc/macmol/<ID>.mmol where <ID> is obviously that of the PDB structure. Despite the extension, it is a plain PDB file. The CRYST1 record (for crystallographic structures) of such coordinates files has been modified to space group P1, since the crystallographic operations of the original structure don't hold. A potential problem if these files is that they don't seem to care about having duplicated atom numbers... These assemblies are most often correct and validated by experiments. However, you might want to add a caveat or, even better, an intermediate window with a link to the place where the PQS explains how that particular oligomer was generated and why it is considered biologically relevant: http://pqs.ebi.ac.uk/pqs-bin/macmol.pl?filename=<ID> Best regards, Miguel - -- Miguel Ortiz Lombardía Centro de Investigaciones Oncológicas C/ Melchor Fernández Almagro, 3 28029 Madrid, Spain Tel. +34 912 246 900 Fax. +34 912 246 976 e-mail: molatwork@yahoo.es - ---------------------------------------------------------------------- Et ainsi ne pouvant faire que ce qui est juste fût fort, on a fait que ce qui est fort fût juste.
