would anyone be willing to share stories of the worst molecular replacement search probes they used to get the correct solution purely with MR? perhaps in terms of %-scattering, RMSD, Z-score, LLG, or other possibly specific scoring values. -bryan

OK, I'm properly chastised - "outlier" does not equal "bad". However, residues which are not flagged as problematic or unusual during validation should not be flagged in the final pdb file. And I have read Gerard's paper, and the molprobity paper. Recently. Sue On Sep 21, 2007, at 9:57 AM,

Has anyone successfully fought this "bad residue" listing? I understand that the pdb wishes to flag problem regions, but this is not a valid way of doing so. I can tell them where the problem regions are in the structure if they wish. oh dear, oh dear - touchy, touchy! coordinate-based valida

Yes, and I just got a pdb file back from the pdb that they flagged with over forty bad residues. The Molprobity plot from the RCSB validation server shows zero residues in disallowed regions. ( I got lucky, I didn't "fix" any bad residues.) For many of these "bad" residues, the position o

Hi, If you checked the Ramachandran plot using PROCHECK, you may think almost all residues belong to the most favoured, additional allowed, or generously allowed regions of the Ramachandran plot that is the part 1 of the PROCHECK output PostScript file. But if you checked the part 2 of the PROCHE

The answer to your question is called Phaser. Using Phaser, you can input multiple search models in one search routine to look for solutions. You should read the online manual and tutorials, if you are not already familiar with Phaser. You can also 'modify' or appropriately 'trim' your search
