easily handles many of the described tasks and does MUCH MORE !

I have a set of utilities for handling PDB files, known as "PDB Pipeline". Each 
one does a single distinct thing: manipulate the spatial coordinates, reset the 
B, pull out a particular subset of residue numbers, fix particular known 
problems, etc. There are several dozen. They work very nicely with Linux 
command line utilities such as grep and sed. They are so old that they were 
written in Fortran-77 (with VMS FORTRAN extensions).

Subject: [ccp4bb] PDBx-format utilities

A spectre is haunting structural biology - it is the spectre of the PDBx
format.

We at CCP4 are interested in providing tools that are equivalents of
those that one might have trivially made with utilities such as grep or sed.

For example:

     delete the hydrogen atoms

     extract the hydrogen atoms

     extract the SD of MET

     find the atoms with B-factors greater than 100.0


So, what useful tool have you made can that works because it based on
the PDB format - that (of course) doesn't work with PDBx?


Thanks,

Paul.
