Does anyone have BNF notation for the atom specification 'language' used by Chimera?
I don't think so. What's the use case here? If you're in the context of Chimera, you should be able to use Chimera's own atom-spec parsing facilities, e.g. chimera.specifier.evalSpec(). Outside of Chimera, I'm aware of a pretty extensive but not totally complete parser in perl: Chemistry::MidasPattern - Select atoms in macromolecules - search.cpan.org --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu
