[chimerax-users] calculate volume of voxels

[Elaine Meng]

If you mean to just find out the voxel size, you can use command "volume settings" or menu: Tools... Volume Data... Map Coordinates.

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.
