Hi Vaheh -
I wasn't saying it can't be done, just that pdbset is my preferred way to
handle renumbering when going in the insertion code --> integer direction.
Within PyMOL, here is one way (you'll have to repeat for each chain you wish to
renumber):
```
# see: https://pymolwiki.org/index.php/Pymol.stored
from pymol import stored
# store the current residue numbers in a list
stored.oldresi = []
iterate polymer.protein and chain L and n. CA, stored.oldresi.append(resi)
# make a list of the new residue numbers
stored.newresi = list(range(1, len(stored.oldresi)+1))
# zip them together into a lookup dict
stored.hash = dict(zip(stored.oldresi, stored.newresi))
# change the residue numbers for each atom in your chain
alter polymer.protein and chain L, resi=stored.hash[resi]
```
Hope that helps.
Cheers,
Jared

Jared,
Are you saying it cannot be done within PyMOL? The ccp4 option is well known.
Thanks.

Hi Vaheh -
Try `pdbset` from the CCP4 suite.
http://www.ccp4.ac.uk/html/pdbset.html#renumber
```
pdbset xyzin in.pdb xyzout out.pdb > pdbset.log << EOF
renum 1 chain H
renum 1 chain L
end
EOF
```
Hope that helps.
Cheers,
Jared

Blain,
The command will not change the numbering of amino acids starting from #1. But
if you got missing ones, like in my case, it will. Except for those having also
letter in the number field. I mean the numbering used for CDRs of antibodies,
not alternatives. Hence, my question, is there a command that will ignore the
letters in the number field and renumber the amino acids in the order they
appear in the file.
Thank you.

Hi Vaheh,
alter vh, resi=str(int(resi)+0)
will not change the residue numbers because 0 is being added.
Replace 0 with your desired residue number offset.
Best regards,
Blaine

Thank you Jarrett,
Then the command
alter vh, resi=str(int(resi)+0)
should work, right? But it doesn’t because there are residue numbers with
letters. Is there a command that will either remove the letters or won’t pay
attention to them and renumber sequentially.

Hello,
The command shown on this page
https://pymolwiki.org/index.php/Renumber<https://urldefense.proofpoint.com/v2/url?u=https-3A__pymolwiki.org_index.php_Renumber&d=DwMGaQ&c=VjzId-SM5S6aVB_cCGQ0d3uo9UfKByQ3sI6Audoy6dY&r=k0gMbcsdOcdbPUNV5tW66KQSZfXL0ewVDPVBp7tqbks&m=HQhXfRvgQZ3mFRTUuOGKZTZZVlTRi9o87ygYqEDnPog&s=ziFhw29qVsmpI-rra_AyanmqFEsNZVmEsXF4VIjUMmI&e=>
is not one that comes with PyMOL by default. Try downloading the script and
importing it via the `run` command in the PyMOL command-line:
run
renumber.py<https://urldefense.proofpoint.com/v2/url?u=http-3A__renumber.py&d=DwQGaQ&c=VjzId-SM5S6aVB_cCGQ0d3uo9UfKByQ3sI6Audoy6dY&r=k0gMbcsdOcdbPUNV5tW66KQSZfXL0ewVDPVBp7tqbks&m=HQhXfRvgQZ3mFRTUuOGKZTZZVlTRi9o87ygYqEDnPog&s=FHmoNz1s1Pj-_paiWCTfneG3RkPiLccu2uI2KNr8ROw&e=>
and then you should be able to use the command as shown on the Wiki page.
Hope that helps,
Jarrett J.

Hello PyMOLers,
Wiki uses renumber command to alter residue numbers, but PyMOL doesn’t
recognize it. Is it that Wiki is old, or my PyMOL version is dusty?
