An mmcif / numbering question...
When specifying residues, chimera seems to use "auth_seq_id" (the authors' numbering), as well as the authors' naming of chains (auth_asym_id).
Is there any way to ask chimera to find residues using "label_seq_id" and "label_seq_id" (the numbering the protein data bank gives) ?
Is the label_xxx information discarded when chimera reads an mmcif file or is it hidden in an attribute somewhere ?
