Hi, I have a question regarding the automatic restraints in Refmac5 and CCP4Interface 7.0.050.
For a few years I have relied on automatic restraints settings in the CCP4I interface which usually resulted in r.m.s. bond deviations of about 0.02 Å and good convergence of refinement (lower R-factors). The last few months this have not been the case. In structure after structure in different projects we get consistently r.m.s. deviations of 0.03 Å and more and lacking or worse convergence. This is not a huge problem since you can get around it by using user set weighting terms. Still it is annoying. Anyone experiencing the same?
