About the unit cell shrinkage: I have heard a lecture (I believe it was Andrea Thorn form G. Sheldrick group on one of CCP4 meetings), where she mentioned a mistake in X-ray wavelenght input (swaped 3rd and 4th digit), which no program from integration to structure solution did not

Dear Tim, I know that it cause rescaling and you don't have to input the number manually most of the time recently. I just wanted to point out that it can obviously happend. The question reminded me Andrea's lecture. Jan On 07/02/2015 10:34 AM, Tim Gruene wrote: -BEGIN PGP SIGNED

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Dear Jan, when you input the wrong wavelength during data processing, you rescale the Ewald sphere construction, i.e. it will result in a different unit cell and crystal to detector distance. I am not sure what you mean by 'which no program from

[COOT] Coot only warns of cis peps on first round of real space refinement?

Hi all, I've noticed that in the traffic light refinement validation dialogue that pops up after real space refinement, Coot warns the user when Cis peptides are introduced (Which is a very good thing!), but it does not warn the user if a cis peptide is already present in the residue range - is

Hi Jan Thanks for the suggestion. I checked AFAICS the wavelength is correct. I think in any case the difference you are talking about would be far too small to explain the effect I'm seeing (the error in the wavelength is ~ 0.01% whereas I'm seeing deviations from the ideal vdW contact of up
