Chimera can measure the volume enclosed in a contour surface using
Tools / Volume Data / Measure Volume and Area
If the density map has a correct grid spacing set (called voxel size in
volume viewer dialog Coordinates panel) then the reported volume will be
in physical units, e.g. cubic Angstroms. If the grid spacing is set to
1 or you divide the reported volume by the voxel volume you can get a
count of the voxels inside the contour.
