Hi Kerstin, "Should I refine a low-resolution dataset 6 A": usually we refine a model of the crystal structure against measured data set. Besides, technically you can do this, and I hope other replies will help you set correct expectations about the realities of the process. At this resolution y

This is a very tough resolution to be working at, but if you want to take it on I'd suggest that xMDFF (http://www.ks.uiuc.edu/Training/Tutorials/science/mdff/tutorial_mdff-html/node8.html) starting from a good homology model is more likely to yield results. Shameless self-promotion: I've been
