[chimerax-users] calculate volume of voxels

If you mean to just find out the voxel size, you can use command "volume settings" or menu: Tools... Volume Data... Map Coordinates. https://rbvi.ucsf.edu/chimerax/docs/user/tools/mapcoords.html 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://rbvi.ucsf.edu/chimerax/docs/user/tools/measurevolume.html https://rbvi.ucsf.edu/chimerax/docs/user/commands/measure.html#volume See also the general page on measurements: https://rbvi.ucsf.edu/chimerax/docs/user/measurements.html Elaine ----- Elaine C.

Thanks for the so quick reply Dr. Elaine.

One more question, can chimera calculate the volume of voxels for density map?

Best, Tianming
