Hi, all the errors go into B and so you can get decent R with wrong structure. Glycosylated proteins have a large component totally disordered - do you see any sugars? with B~133 you uj is 3.7A which means that atom is all over the place and meaningless As a reviewer I wo

Is it the gui or mosflm itself that crashes? The new gui is dependent upon a number of external dependencies, so you are at the mercy of the stability of those. The old gui still works fine, at least last time I checked. On Thu, July 30, 2009 4:40 pm, Marius Schmidt wrote: > We have a little

Dear Marius, 'crash' is a very general term. Maybe you could describe at what stage imosflm crashes? Is it reproducible or does it crash at random stages? When you start imosflm from a terminal, what are the last words printed to the terminal? Are there any log-files that might give a hint as t

Dear Ewa, I can model a 3 residues sugar chain in the glycosylated protein. The structure was build with an identical 2.3 A resolution structure as model. The final structure is nearly identical with its model. So I think the model is not wrong. The data was collected at 100K. During the refinement

We have a little internal project where we want to compare the quality of data reduced with HKL2000 and IMOSFLM (mosflm) to 1.3 A. Unfortunately, imosflm with its standard settings crashes always even at lower resolution whereas HKL2000 is rock stable. Why is that so? Any experience with that?
