Dear all Thanks for your replies. And thanks to all those who noticed that I had posted wrong unit cell dimensions for P3221 (which I picked from the header of the template pdb).
My space group is P3221 (unit cell 54.8 54.8 100.1 90 90 120). Data quality appears fine. I/sigI=4.9; Rmerge=0.088; Completeness=99.9 (outershell values are: 2.3; 0.333; 99.9 respectively) As mentioned above, I solved the structure by molecular replacement and there appears to be no twinning. There are no major unmodelled densities. A couple of small blobs are present, which I think may be glycerol or some other molecule from my crystallization buffer but I still need to model these. Other than that, there are no major issues. I was just wondering if the present R-factor values seem alright for a 1.9 ang data, which many of you have suggested it does? Thanks again. Any other suggestions/comments are still welcome.
