Dear Ariel

I2 (== I 1 2 1) is the same space group as C 2, but with a different setting of the h & l axes. You can use either, or you can force Pointless to choose the C2 setting

Best wishes

Hi there,

I am integrating, with imosflm, a datset divided high and low resolution datasets. I first integrated the high resolution one in C2, but after running Pointless it suggested I121. The same happened during the low-resolution data integration, but the cell parameters are slightly different respect to the hi-resolution data. Should I fix the cell parameters during the integration of the low resolution data to the parameters obtained from the Pointless corrected hi- resolution integration?

How often happen that pointless suggest a different space group respect to the cell refinement space group?

Thanks a lot in advanced.
Best,
Ariel
