-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Deepthi,
is it just a typo, or do your last two sentences say that your data DO NOT scale in P312 but scale well in P321? Did you try pointless for space group determination? I have not used molrep for this purpose and cannot judge how reliable the self rotation function is for space group determination. Depending on your resolution and cell dimensions you may have very few reflection for determining the screw axis. Do your data suffer from radiation damage, does the cell become greater during integration? Did you fix the detector distance during integration?
