Hi

I think I'd say there was no hard way to do it either, before that stage (of course, I woudn't want to be too dogmatic about that, because that would be entirely out of character ;-).

Thanks for all the replies.

I guess there's no easy way to distinguish between the two space groups before obtaining an electron density map.

Cheers.

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.

Rafael.



No is the short answer..
If you have heavy atom data with anomalous scattering you will get better maps in one than the other..
