Hi Xiang,

why not? You can arbitrarily choose one model and map as a reference and overlay the rest over it. Phenix tools such as "Structure comparison" or lower level ones such as phenix.superpose_maps and phenix.superpose_pdbs should help here. Nat spent time on this so I hope he offers more advice on this once he sees this email.

If (and only if) nothing helps please feel free to get back to me and I may provide with a custom script to accomplish this task.

Hi everyone,

I am working on a series of crystals with overall same framework structure plus a different extra part which attaches to the framework. I want to compare the electron density maps of the crystals by overlapping the frameworks and see how the extra parts differ from each other. Is there a way I can do it?

Thank you very much for your help!

Sincerely,
Xiang
