Re: [ccp4bb] refine an ion atom with different status

2014-06-19 Thread Pavel Afonine
Hi Bernhard, phenix.refine makes use of charge if specified in PDB file (rightmost column after the chemical element type) to use appropriate form-factors. However, occupancies and B-factors are very efficient mops to accommodate a broad range of discrepancies between model and reality. So whether

PS: Just to clarify, my conclusion as to the usefulness of the program is based on results obtained in a shared research project. I did not directly use the program myself. Cheers, Navdeep On Thu, Jun 19, 2014 at 10:47:17PM +0200, Navdeep Sidhu wrote: > Dear Antony, > > In addition to other go

".. change the valence of ion or metal except by changing the occupancy" Changing the occupancy is entirely different from changing valence. The former scales the scattering function proportionally, while the elimination of outer shell electrons predominantly reduces the very low resolution par

Hi I also encountered the same problem after recent updates (not the most recent one, but a couple of updates back). Choosing to run old-truncate will get it around. Best wishes Jie - Original Message - From: "" To: Sent: Thursday, June 19, 2014 1:11 PM Subject: [ccp4bb] ctrunca

Dear CCP4bb, I am experiencing an unusual error when running truncate. The program appears to be converting I's to F's, but then failing to output them in the resulting mtz file, see mtzdump output below: Col SortMinMaxNum % Mean Mean Resolution Type Column num

Dear All, Sorry for spamming. Thanking to the criticism and advices from a number of recent testers (in particular, Mark van Raaij, Oleg Sobolev, Pavel Afonine), we produced an updated version (version 2.3) of the program EFRESOL to calculate the effective and optical resolutions and the anisot
