Hi Bernhard, this is for papers, not for manuscript. 25 bucks is quite dear to print an already published manuscript, as much as I understand that Yeti wants to read your output. Cheers, Tim On Tue, 22 Feb 2022 12:00:54 -0800 Bernhard Rupp wrote: > Glad to bring this opportunity to your atten

Dear Renu, Bernhard is probably on the right track. It is likely that your crystal diffracted to substantially higher resolution than 1.7A, and that its diffraction was sharply truncated by the edges of a detector placed too far. If so, the sharp truncation in reciprocal space of the Fourier

Hmm…compliment, pretty darn good density map for 1.7 A….maybe look at the resolution cut-off. If it is at a significant level, it could be truncation ripples? Otherwise I second the noise opinion if it is already a well completed model. Cheers, BR From: CCP4 bulletin board On Behalf

or perhaps something in the non-visible part of the ligand pulling electrons out of the rings? can this somehow be specified as ligand input? on the other hand, I guess this is near the "end" of refinement, so the Fo-Fc difference map is probably very flat - meaning that 3 sigma corresponds to ve

I thought it was tryptophan but the nitrogen and extra bond are in the wrong places so it must be a ligand and, if so, have you tried refining the occupancy? Cheers, Jon.C. Sent from ProtonMail mobile Original Message On 22 Feb 2022, 05:34, S wrote: > Hi All, > > I am getting
