[Chimera-users] Sidechain selection in Python

[Eric Pettersen]

Hi Stefan,
	OSLSelection can only handle the "#0:30" part of the spec -- it doesn't handle intersections, named selectors, etc.  What you need to use is chimera.specifier.evalSpec("#0:30 & without CA/C1'"), which returns an ItemizedSelection.
