Dear Bob, I am quite puzzled by the results you describe. Here are some of my questions/comments: - You could index in P2 and in P222. I assume you have in both cases the same cell dimensions and for P2 beta very close to 90°? - How do the diffraction images look like? I would check every

Dear Paul, I, and probably many coot users, would appreciate it very much if you could add a create covalent link option in coot instead of having us wade through 8 pages of instructions and hoping that we put exactly the right number of space characters in the link record. Best regards, Herman

Dear Rafael, dear Li Chan, is this the first time you run arp/warp on that particular computer? Maybe the architecture of the binaries are not the correct ones. You might search for the 'snow' binary (which leaves the empty log file) with the command 'find ./ -name snow' issued from the arp/warp

Dear Raphael and others who experienced this, in some rare cases we have seen that the 'restraints' module of ARP/wARP can have a malfunction. If this is the case for your data, then the best you can do at the moment - while the fix is not there - is to deactivate the use of this module in

I am going to try to guess in this one. As you say, the positions of the iodines cannot be challenged. But maybe their occupancies can. Is there anomalous signal from iodine at your wavelenght? Are you expecting radiation damage? In any case: I see a spherical shell of low density around each one

Hello, the guess about ripples is most likely correct. Just do this simple experiment: place one iodine in a middle of a cubic box and compute F-calc map. You will see mazing picture! At least I enjoyed. You will see a number of concentric shells of density around iodine, positive and
