Hi Prathvi, Yes, either one.
In Chimera, they are automatically calculated when you show a molecular surface. It creates an attribute named areaSAS, as explained here: < https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/representation.html#surfac...
See also this previous chimera-user post on using Chimera to get a list of residue SASA values <http://www.cgl.ucsf.edu/pipermail/chimera-users/2018-June/014729.html>
(If you use this page < https://www.rbvi.ucsf.edu/chimera/docs/feedback.html> to search chimera-users by "sasa", that was the top hit)
In ChimeraX, you would use the command "measure sasa" <https://rbvi.ucsf.edu/chimerax/docs/user/commands/measure.html#sasa> ... then save attribute "area" to file <https://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html#attributes>
I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hi Elaine, Can I use chimera or chimeraX to know the solvent accessible surface area (SASA) for selected residues?
