Hi Vennila, I would suggest running phenix.xtriage on your data, and examining in particular its analysis of 1. twinning 2. possible space groups (are your certain that there is a screw axis?) 3. measureability of anomalous signal as a function of resolution In 1.4-4 you may have to run both p43212 and p41212 (current versions do this for you). All the best, Tom T
Dear members,
I am using phenix1.4-4 version. In autosol, got the score of 10.24 for one iodine soaked data. FOM:0.27 and only 54 residues ( that too wrongly) were built out of 129.(CC=0.4), R=0.49 and Rfree=0.574. Regrading the data quality, Rsym:0.0448, Ranom:0.055, Resln:25.0-2.6A Spacegroup is P43212, completeness:99.4%, Multiplicity:11.7, anomalos signal is 1.52 at lowest resoln and higher in high resolution shells.
What might be reason for not able to solve this structure?
