Dear Yocheved, I think you would have to cut off the X,Y data using Region min,max so that the size is 108,108,108. As far as I know, Chimera doesn't have a feature to add grid points with zero values to make the Z dimension larger, which would allow creating a cube without losing X,Y data. Although there is a "vop boxes" command to extract cubic boxes, it does not extend beyond the current data. Although there is a "vop cover" command to extend a map, it assumes periodicity (wraps the data around instead of adding zeroes), which does not sound like what you want. Elaine ---------- Elaine C.

Hi Can I please get your help with map resizing. I have a map with a box size 250,269,108. To run a map fitting script I need the map to have a cubic size. Using the volume viewer- Region min max step x - I was able to play with the box size the problem is I can't get the entire map into a cubic box (Z axis is to small). Is there a way to enlarge the box on the Z axis?
Thank you Yocheved
