Dear VMD users,

I have a DX file of volume data for isosurface visualization. The
volume is a cube centered at the origin. How can I choose half or 1/4
of the volume data for visualization? For atomic structures, atom
selections like "Z > 0" and "X > 0 and Z > 0" can be used for this. But
I can not apply similar selections for the volume data. Does anyone
know the options to do it?
