I would expect that if you found HA sites in C222 then they must obey
C222 symmetry?
Why not just repeat the search in C2221 and see if you get a better answer?
Going back a stage:
Arent you able to guess whether there is a screw axis from your absences
along 00l?
Pointless gives a good analysis of likely SGs from these sorts of
considerations.
The results are good if
a) you have actually measured the 00l line, and
b) you dont have a non-crystallographic translation with coordinates,
x,y,1/2.
Both ctruncate (part of the scale and merge task) or sfcheck will test
for this.

Hi all
I did some HA searching and found some sites in C222 that seem to be
NCS related. Any ideas on how to determine whether or not the space
group is really C2221 from these sites?
Thanks
