Hi all,

As discussed on the ccp4bb (https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ccp4bb;2223469c.1511), the mmCIF format incorporates an atom_sites_foornote record (http://mmcif.wwpdb.org/dictionaries/mmcif_nmr-star.dic/Categories/atom_sites_footnote.html) which allows for the direct association of specific comments/annotations with particular atoms/residues.

As part of expanding mmCIF support in Chimera2, would it be possible to consider incorporating the capacity to read, write, and display these records as labels or notes? This could be a great way of incorporating built-in-annotations in a structure pertaining to specific features that could potentially be readable by other software such as Coot and pymol.

Cheers,
Oliver.
