These structures are horrible.. Remember you do not know your spacegroup. Absences along 0k0 and 00l will be very influenced by the translation. Sp you need to test all: P21 2 2 P21 21 2P21 2 21 P21 21 21 Run MOLREP using the pseudo translation vector - it is an option in the GUI under

Peter, I had a similar case, but the centering was pseudo-I in the monoclinic system (Oksanen et al. (2006) Acta Cryst. D62 1369-1374). I don't think you need to delete any reflections for MR; you should have higher than normal correlation coefficients as well as R-values. If you see

Hello, I posted a message about this a month ago and thanks to everyone for their responses. At the time, I did not fully appreciate the problem I was dealing with so this time my question is much more specific. I would very much appreciate your help as this structure is turning out to
