I was wondering if anyone knows how to tell how many voxels within a bounding box can be assigned to protein signal instead of "empty space" at any given contour/density level? Thanks, Steve Kolodziej

Hi Steve, Chimera can measure the volume enclosed in a contour surface using menu entry 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. Tom
