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#surfaces> 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.

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