That's good to know, Rhys. But would you mind sharing why did it work with Balbes? Is there a big change in the position of the domains as related to your first searching model, or huge loops that had been removed? Carlos Em 02/10/2012, às 14:42, RHYS GRINTER escreveu: Thanks for your

[ccp4bb] How to output water molecules with Phaser?

2012-10-02 Thread Koji Yonekura
Hi all, I am using Phaser 2.5.1 for molecular replacement. I like to keep tightly bound water molecules (HOH) in the input pdb file. Phaser 2.1.4 outputs all HOH lines in the input pdb file to the output pdb file, but Phaser 2.5.1 doesnot. I am wondering if there is any way to carry input HOH

2012-10-02 Thread Randy Read
As a deliberate choice, we changed Phaser so that it would omit all HETATM records from the model used for molecular replacement. This was largely because when extensive water structure was carried along, it could mess up the molecular replacement calculation. However, if you want something

Hi Randy When you say carried along are you saying that they are used as part of the molecular replacement search? Or are they temporarily put aside and them simply added to the PDB in frame with the molecular replacement solution (but are not part of the weighted structure factors output in

Dear Randy, I just noticed that Phaser 2.5.1 sets the occupancies of attached sugers e.g. NAG, NAM etc. to zero, which caused Buster to crash. Resetting the occupancies to one solved the problem, but other refinement programs may not crash and may cause people unknowingly carrying on zero

Hi Faisal, There is no such thing as the ideal deviation from ideal geometry. As long as your rmsZ values are below 1 (which they are), it's okay. Note that, in contrast to popular belief, rmsd has no useful meaning for bonds and angles. Genarally, rmsZ goes down with resolution but the
