[ccp4bb] Error in ccp4lib?

2014-03-24 Thread Zbyszek Otwinowski
I am reading an external file, which contains phases and ABCDs in the space group P43212. My file has an asymmetric unit with k= h. Since CCP4 uses a different asymmetric unit with h=k, this requires phase and ABCD coefficients transformation. The transformation seems to be correct for

You don't say how you are doing the transformation? I would simply input the file to cad cad hklin1 thisfile.mtz hklout newfile.mtz labi file 1 allin end I think (and hope) that the data and phases will be converted correctly to the CCP4 asymmetric unit. Eleanor On 25 Mar 2014, at 09:16,

Centrosymmetric reflections typically have C=0 and D=0, although non-zero values should not matter, as they do not modify phase probabilities for centrosymmetric reflections. Somehow, entering non-zero values for C and D for centrosymmetric reflection creates strange results during
