Re: [ccp4bb] A question on the diffrentiattion of the salt crystal and salt diffraction in the protein metal complex

Dear Acoot, Just to add to other good ideas, you could also try to index your frames, find the cell parameters, check them against one of the relevant databases (CSD, ICSD; see or COD, , which unfortunately is still

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Dear Acoot, the positions of the reflections on the detector depend on the unit cell dimensions, but not at all on the content of the unit cell. Therefore a protein crystal with a rather large cell produces a large number of reflections per image. A s

[ccp4bb] A question on the diffrentiattion of the salt crystal and salt diffraction in the protein metal complex

Dear All,   Suppose I have a crystal hit from the protein-metal complex, with the possibility of that the hit is a salt crystal. When I diffract it by X-ray, I got some metal (or salt) diffraction without the protein diffraction (maybe due to too low protein resolution). Will you please tell me
