[Chimera-users] vop morph map color

Hi Henning,
I believe map morphing requires the input maps to have the same grids, but you can resample a map onto the grid of another (making a new map that is congruent with the second) using command "vop resample":

That's probably the best approach if the main purpose is to get the same grid so that you can do morphing.

More generally, cropping and writing out the cropped region can be done using the Volume Viewer tool  (see Features menu "Region bounds" and/or "Subregion selection" and File menu "Save Map as...")

... or the corresponding options of the"volume" command

For general zero-padding, I guess it could be done with "vop cover" although that is not the command's main purpose.

I hope this helps,
