Dear all,
Running BP3 for SAD data, but fail, the error message shown as follow:
Dose anyone know how to fix it?

Dear CCP4BB members,
We would like to identify a ligand that is present in crystal structure
(according to strong positive densities at active site) but absent in
crystallization condition. We already have some candidates in mind based on our
knowledges on this protein but we need to validate
Hi Zach,
It seems the residues which you are discussing belong to an helix. It is
not clear what is the present Rfree, however the residues side chains are
not properly fitting. Did you use real space refinement in coot using helix
secondary structure constraints? Hopefully it will push Asn
Hello again, and thank you for your quick replies!
For your consideration, I have added a representative .mtz and .pdb to my
shared dropbox folder

Dear Matthias,
the idea of paired refinement is to quantify the amount of information in your
structure. For that purpose it is most likely counterproductive to disturb
your parameter at all! In the worst case you end up comparing different
structures.
Use the very same structure, do not
Dear Asmita, (and all who may be interested)
In Gourinath & Himmel et al. Structure 11:1621-1627 (2003), I normalized

Any such analysis must be viewed with caution, of course, because it
Thanks James for your reply. I my naive way, I thought that when doing paired
refinement, it would be sufficient to run several cycles of refinement with
simulated annealing followed by a thorough real space rebuilding. What is your
thought about using the "jiggling" of additional cartesian
Dear Members,How well is extinction coefficient based protein concentration
measurement accuracy established. It seems that several monograph based protein
HPLC assays use 214 for the same. How accurate are extinction coefficients for
the same proteins. Is there any consensus if which one
