[Chimera-users] Is it possible to dump out the SAS surface points calculated by ChimeraX?

Hello Francois,
(There is a chimerax-users e-mail list, CC’d here.)

Note that the surface displayed in Chimera and ChimeraX is the SES, not the SAS.  For spacing of points, see the “surface” command option “gridSpacing” — use ChimeraX command “help surface” or view the help at our website:

Use ChimeraX command “save formats” to see what formats you can save.  STL or X3D would include the surface vertices, I believe.  For full details on “save” use command “help save” or see the copy here:

I hope this helps,
