Dear ccp4 members
I have question about how to interpret polarrfn log. I wish to know if my
crystal display NCS. I am not sure how to interpret the file. I see it have two
peak, one is origin and the other is not that high to me. I have attach copy of
the file. If someone could assist me to understand the file it would be
appreciated.

Well - a peak of 29% of the origin is reasonably significant at 2A
resolution.
This indicates a non-crystallographic 2-fold axis in the a-b plane
( the multiple solutions are all symmetry equivalents..)
omega phi kappa
Peak 7 1 1 0.0 0.0 285.3 29.5 180.0 180.0 74.7
1 2 0.0 180.0 254.7 29.5 90.0 142.7 180.0

How many molecules do you expect in the asymmetric unit.
