I have collected few diffraction data sets for the same. Every time I collect a data set I find that the crystal is diffracting at different angles only in one particular direction, the z direction. These are few examples for the native data sets I have collected. Native crystal: space group P 31 2 1 48.52 48.52 161.90 90 90 120 P 31 2 1 48.94 48.94 169.89 90 90 120 P 3 2 1 48.40 48.40 154.48 90 90 120 We see similar pattern in SeMet crystals too. Thus, it becomes difficult to merge the native and SeMet data sets. Is there a way to get around this problem? I am looking forward to suggestions. Megha
