[Chimera-users] Offsetting residue numbering

[Elaine Meng]

Hi Sumitro,
I would renumber the residues in the input file before opening it in Chimera.  Of course, manual editing is too tedious.  One of these web servers for PDB editing may be the most convenient:

<http://www.igs.cnrs-mrs.fr/Caspr2/magicPDB.cgi>
<http://dicsoft2.physics.iisc.ernet.in/pdbgoodies/inputpage.html>

Uh-oh,  the second one is unreachable currently.  I'm hoping it's temporary... but at least the first one is still there.

I believe they both make you choose or upload the file before you can see the options, but can  do several things, including changing chain ID and renumbering the residues.
I hope this helps,
Elaine

I can't do it manually cos there are many residues. Is there an easy way to resolve this other than using a script to automatically assign the labels? It'll be good if i can resolve this from the root , such that my atom specification is also consistent with the naming convention I use. :)
