[chimera-dev] attribute for selection?

HI, I want to add attributes to atoms that are selected and those that aren't. I thought that atoms had a selection attribute already defined in chimera (something like a boolean) but I don't find it. I am wrong with that? best, JD Dr. Jean-Didier Maréchal Lecturer The Computational Biotechnological Chemistry Team Unitat de Química Física Departament de Química Universitat Autònoma de Barcelona Edifici C.n. 08193 Cerdanyola (Barcelona) Tel: +34.935814936 e-mail: JeanDidier.Marechal@uab.es www: http://asklipio.qf.uab.es
