Re: [ccp4bb] Hydrogens in PDB File

Clearly, it is a good idea to keep hydrogens: http://phenix-online.org/presentations/hydrogens.pdf Not sure why this keeps coming up as a topic given how much it was said about it in the past, all the MolProbity arguments, etc.. Issue of missing side chains and loops is tricker indeed. Pavel

Dear Thomas, Thank you for the explanation. I use an old version 1.7.2.3, and I believe that the problem is fixed in a newer one. What about residues with missing side chains? How are they treated when a surface is calculated? I began placing the "riding side chains" into my models to avoid

Dear Dale, You raised a very important issue that has been overly ignored by the crystallographic community. The riding hydrogens are just a tip of an iceberg. It is absolutely unclear even to an experienced crystallographer how to treat poorly ordered side chains or even whole residues. As a

While we're at it, it would also be a great improvement if the PDB would list nominal resolution in all 3 directions for structures with significantly anisotropic data. I'm never 100% sure what to do in those cases. Thanks, Phoebe ~~~ Phoebe A. Rice Dept. of

Dear Tim, I am in agreement with Ethan and you that a complete description of the restraints and constraints applied to the model should be included in the deposition. This is currently a major failing of the wwPDB. For hydrogen atoms we, at least, have the "Riding hydrogen atoms were added"

Re: [ccp4bb] dimple, skip pointless?

Dear Guenter, No, unless you intend to start with MR (option -M0) -- in such case pointless is not run. I could add such option, although it may take a while before it's done and before it goes as an update to CCP4 7.1. Do you want to skip pointless to save time, or you get wrong result? Best
