Hi gurus!
I need to do some modifications in a set of 20k PDB files for the same complex (solutions of Brownian dynamics) so that they are suitable for runnig some calculations in a NMR prediction program.
To do that, I'm using BASH. One of the modifications that I need consists of renumbering residues from a certain point (not all of them), because I need two chains with consecutive residue numbering. I'm trying to do it with awk, but I can´t find the way to do it.
Any help?
Thanks in advance!

One of the programs I find useful for manipulating PDB files is pdbset, which is a part of the CCP4 package.
For example, to renumber a file 1xyz.pdb so the first residue number is 1, this is all it takes:
pdbset xyzin 1xyz.pdb xyzout 1xyz_renumbered.pdb << EOF
renumber 1
end
EOF
You could easily write a small script that would do this for many files automatically.
A simple Google search turns up bunch of other solutions.
