4164	SHEET information is keep nor maintained	Greg Couch	Eric Pettersen	"When outputting mmCIF files, the sheet information is not given because ChimeraX's internal data structures don't have that information.  So, effectively, each strand is its own sheet.

This could be mitigated if the AtomicStructure::compute_secondary_structure function had a way to ssave the report as a Python data structure and if sheet names were not limited to one character.  Then the mmCIF writer could compute the sheet information and save that.  It wouldn't necessarily match the current secondary structure assignments, but it would be better than just having strands."	defect	closed	major	1.3	Core		duplicate						all	ChimeraX
