[Chimera-users] SASA calculation per residue

Hi Andrew,
Your command attempt mystifies me, but I’ll go on the rest of what you said…

Just show a molecular surface (e.g. with command “surface”) and then save a file with the list of residue SASA values.  You would save that file using the Render by Attribute tool (in menu under Tools… Structure Analysis); in that dialog’s menu choose File… Save Attributes.  In the attribute-saving dialog you have to specify which attribute you want: “areaSAS” of “residues” (there is also the same attribute name for individual attoms)

Attribute-saving is described here, in the bottom section of the page:

There is an option to restrict the save to the current selection, if you don’t want the list for all residues.
I hope this helps,
