Hi,
I am in doubt between the enamtiomorph space groups, p6522 and p6122.
Is there a way to distinguish the correct one in the absence of a
molecular replacement model?
Cheers.

You cannot distinguish by absences. How do you plan to phase? I would
say choose one space group - and if you get left handed helicies - you
guess wrong... (yes - the automated phasing software will try both and
calculate which you should use based on other statistics)...
If you want to gamble - go w/ P6122... Data from the PDB indicates that
there are 1.5x as many proteins w/ P6122 vs P6522...
