Dear Rohit,

Try to run sfcheck or XTRIAGE and check, if your data is fine. Check for
twinning or pseudo-translation. You can send your processed mtz to me and I
would be more than happy to help you.

You can look into cumulative intensity distribution (if you processed with
XDS, it will be in CORRECT.LP file) and it will give you indication of
twinning.


Thank you
Rajesh
