Also, I notice that there are some python modules in chimerax, can I import them in to my own python code ?

It depends on the contour level of the surface, of course. Elaine

Not only the voxel map, but also the whole region of the map, for example the colume of the blue region in the following fig. <image001.png>

If you mean to just find out the voxel size, you can use command "volume settings" or menu: Tools... Volume Data... Map Coordinates. <https://urldefense.com/v3/__https://rbvi.ucsf.edu/chimerax/docs/user/tools/m... >
If you mean to measure the volume inside the surface (cubic angstroms) then command "measure volume" or menu: Tools... Volume Data... Measure Volume and Area. <https://urldefense.com/v3/__https://rbvi.ucsf.edu/chimerax/docs/user/tools/m... > <https://urldefense.com/v3/__https://rbvi.ucsf.edu/chimerax/docs/user/command... >

Thanks for the so quick reply Dr. Elaine.
One more question, can chimera calculate the volume of voxels for density map?
