Please see this information on “saving maps after fitting” (near the bottom of the page):


Basically you need to resample the fitted map on the grid of the other map.  The link above gives more details.

I hope this helps,

I could open these two maps in chimera and align them by map fitting. However, after I matched one of them to the other and saved the map, the re-opened map was still at the same position as the previous! So do you know how to same the map after fitting?
