Hello all:

We have a water density map calculated from a simulations; the voxel
elements represent the frequency of oxygen atoms at a given location.

We can visually see some high-frequency hydration sites, and would like
to know what the spatial coordinates (x,y,z) of these elements. 

Is there any method for VMD to report out the information of a specifc
voxel(s) from a volume loaded into a molecule?

Thank you! If there isn't, I can always find another approach (like
