Hi,

I am trying to select  subregions in two density  maps using the subregion selection option in the volume viewer.   When selecting the  same subregion  different sub-volumes  in the two maps are selected (there is a displacement between the ROIs along  the Z axis) even though the two maps  are aligned to each other (or appear to be aligned in the display window).   Both maps are in the MRC format and both have a voxel size of 2A/pix. ?    Ideally what I want to do is to select equivalent regions of the two maps and then save them as new density maps.   How can I best do this?

Thanks

Hernando.
