15522	Mismatch of crosslink positions when loading structures from PDB-Dev	Georg.Kempf@…	ben@…	"{{{
Hello,

I wanted to report the following potential issue. When loading a model from PDB-Dev that contains crosslink restraints in the IHM format, the crosslink positions sometimes are not matching the model residue numbering. From my understanding, this is because the pdb-dev/ihm format requires the crosslink positions to be given with “_atom_site.label_seq_id” numbering (referring to “ENTITY_POLY_SEQ” list) which can have an offset to the “_atom_site.auth_seq_id” representing the actual model residue number. Hence the crosslinks are displayed for the wrong residues.

An example would be one of our structures:
https://pdb-dev.wwpdb.org/entry.html?PDBDEV_00000210


Best regards,
Georg
