Thanks very much to all who replied, I am now quite confident that as
suggested it is in fact P21 not P212121. My confusion was that initially
the indexing shows that P222 is a very likely spacegroup and the beta
angle is around 90.5. When I managed to get scaling to use the reject
file with less than 50000 rejects the data seemed to scale nicely and
was used for a successful molecular replacement.
However, I re-processed in P2 and then scaled in P21 and the number of
rejects was around 10 fold lower. I now have a very convincing 2.5A
dataset:)
Thanks again,
Mike Swan.
