[Chimera-users] morph volumes after alignment

believe you need to resample the fitted map on the grid of the reference map to create a third map. Then you will have two maps on exactly the same grid (the reference and the third map), and can morph between those two.
For example, if I fitted map #2 onto map #0, I could resample it to create new map #3 with command:
vop resample #2 onGrid #0 model #3
Then try morphing between #0 and #3.
I hope this helps,

However, the volumes are not perfectly aligned in first place. So I align all of them on one of the maps using the “fit in map” functionality. This works great and when I look through the different structures with the volume viewer, they are perfectly aligned. However, if I morph through the maps using the following command:
