Re: [ccp4bb] CC-half value ??

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

Re: [ccp4bb] PEG dependent structural changes in crystal structure

Hi Shiv, Michael has made good points. Also I found similar case, i.e, different loop and active site catalytic residue conformations with slightly different PEG 2000 mme concentration. In my case the catalytic residue moves away from active site and the loop more disordered in lower PEG

Re: [ccp4bb] cryo for high salt crystal

2012-07-10 Thread conan
Min, In some of my Xtal conditions, I only have 1.5 to 2M AmSO4 without KCl, the salt comes out of solution only after maybe several minutes which is enough to harvest the crystal. Maybe you could just direct freeze to try the diffraction since it is already at high salt concentration or maybe

[ccp4bb] How to evaluate Fourier transform ripples

2011-07-06 Thread conan
Dear All, Hi. I was asked in a manuscript revision to discuss about the possible effects of Fourier transformation ripples on the crystallographic results. Specifically, the reviewers question whether ripples may affect on the electron density around heavy metal center which has a
