Here is a question raised by a colleague on the ccp4 bulletin board. Since Chimera was mentioned in his post I thought you guys might have an answer to his question (positive or negative), hence I'm posting his message here.



I am working on a protein whose EM model has been built long time ago. 
The crystal structure has been solved recently and I want to know the 
difference between the crystal structure and  EM model. Unfortunately 
there is no data in the EM data base, so I can not use Chimera or Phaser 
to fit the crystal structure into the EM electron density directly. My 
friend downloaded  the VRML file of the EM model ,which can be viewed 
using Cosmo player. And I can make VRML file from my crystal structure 
using Pymol or Chimera. My questions is:  can I superpose two VRML files 
which come from EM and crystal models? If so, how can I do that?
Thanks in advance!
Best wishes
