Hi Shen, I agree with Eleanor that the split spots will cause worse statistics, but should not be a reason for molrep to fail. What I would do: Molecular replacement with a resolution cut of 3 or 3.5 Å. Process and run molecular replacement in P1. You may have some tricky pseudo-symmetry. With

Hello Eleanor, I used the solved one as the input model. The space group of the solved crystals are: P1 21 1, and P 21. I will turn the anomalous processing off. Thanks, Shen On Mon, Nov 11, 2019 at 10:40 AM Eleanor Dodson wrote: > Why dont you use one of your solved structures as a model?

Why dont you use one of your solved structures as a model? What space group are the solved ones in? The split spots are not good, but they are well separated and integration programs are not bad at such spacings? And your R merges etc look OK. Just a Q - why turn off the anomalous processing. You

Dear Eleanor, Considering some (potential) very strong model bias here: is the difference mFo-DFc map totally flat or just not shown in your picture? Does the density come back as such if the three waters are removed? Cheers Clemens On Thu, Nov 07, 2019 at 01:12:14PM +, Eleanor Dodson
