[Chimera-users] UnitCell.molecule_center(): Attribute does not exist

[Tom Goddard]

Hi Alex,

   There were in fact two problems in the unit cell example code caused by changes in Chimera Python APIs over the years.  I’ve updated the example — the web site will be updated over night.  The fixed code is attached.  Thanks for reporting the problem.

	Tom
