Dear User, I'll appreciate your help. I've worked with Chimera previously, but have not used it recently. Now I try to repeat some of the analysis I've done, but I don't see the option ,solvent accessible surface, in the software (I guess I've installed a newer version). I would like to color all the exposed (to the solvent) residues like in the image below and export a table with these values per atom and residue. [cid:7c648fa9-c7cf-4dab-bf40-f0b4a95b8f47] What I tried to do this time is : 1. Show a molecular surface.. 2. Depiction --> render by attr , when attr is set to areaSAS on residues [cid:f46b071c-36ab-4792-bfc2-31eb50fc2be3] The result I got was: [cid:6b44e796-b2c2-42f8-aac8-1ab725121d38] Am I doing it right? how can export the calculated areaSAS per atom and residue from chimera? How the SAS values calculated in Chimera? Does the higher value means that this residue is more exposed? Thank you for your help, Anastasia
