Dear all,

Does anybody know some softwares for aligning electron density maps?

I tried transforming map by SQL model fit extension in COOT, which turned out to be not working: the map it transformed is the one supposed to be fixed. If I switch the moving model with the reference model, I only got some error messages.

I also tried the "Superpose maps" utility in PHENIX, however, since they are nucleic acid structures, it seems that the sequences cannot be recognized.

Thank you very much!

Best,
Chen
