Dear all, I am looking for some suggestions here. I have lately collected some datasets but the spots are very very weak... it is very difficult to process them. At times it looks like XDS is stalled or at times it just says that it can not interpret the lattice parameters... also while running integrate I have such a message after each range of images:
!!! WARNING !!! REFINEMENT DID NOT CONVERGE LAST CORRECTION SHIFT WAS 9.1E-03 (should be < 1.0E-03) I guess this is not good at all. And I wonder what to do? Is there any info that I can get out from these data at all? or rather not? I wonder if the problem is to find the spots, I have tried with HKL2000 and it can't even find enough of them for indexing. Any ideas are welcome. Best wishes, Almudena. -- Almudena Ponce-Salvatierra Macromolecular crystallography and Nucleic acid chemistry Max Planck Institute for Biophysical Chemistry Am Fassberg 11 37077 Göttingen Germany
