Dear Bert That is a limitation, I agree. Suffice to say the clarity of details seen, or not seen, will not get better in the 'real' situation. The resolution 'limit' based on CC 1/2 also now needs to be considered (in addition to I/sigI criterion). John On 17 Apr 2015, at 17:59, Bert

Good morning Pavel, That's interesting. In our study 'ghosts' of waters in our truncated maps did not occur. Waters and hydrogens behave differently as ghost objects presumably? Greetings, John On 17 Apr 2015, at 20:10, Pavel Afonine pafon...@gmail.com wrote: Hello, John, the

Dear all, While refining the structure of a protein I’m facing problems with some residues present in the loop region of the protein. There are four residues in four different loops in the protein which is always showing as outliers in Ramachandran plot even after multiple steps of refinement
