Hi Zongli,
Happy new year!

The main issue is that the map file format doesn’t include rotation information.  If you rotated your map to go with some atomic structure (PDB file), it is better to save a new PDB relative to the map instead.  If you rotated your map (“map1”) to go with some other map (“map2”), you could create a new map (“map3”) by resampling map1 on the grid of map2 with the “vop resample” command.

Please see “Saving Maps After Fitting” here for the details and links:

I hope this helps,
