Hi Todd, Do you mean reversible or irreversible dimers? If the binding is reversible, then once crystal growth starts, Le Chatelier's principle should take over, pull the equilibrium toward monomer, and you should see minimal impact of dimer on your "monomer crystals". The same would be true in r

Hi Faisal, CC-half standard is valuable in evaluating the cut-off of highest resolution. Sometimes even if I/sigI is close to 1 and completeness is not as high, if CC-half is still significant, it may be worth incorporate the extra high-res shell data and extend the resolution. Again, if only

Dear Faisal, at 2.6A resolution I would not call 23A^2 and 24A^2 'a difference', rather a fluctuation. Parameters are not totally independent from each other and not from experimental issues. It most likely also make a difference which program you use. Some program has a upper cut-off of 100-200 (
