chain starting number once the chain is already created

Yes, the synthax is:

chain.renumberResidues(offset, start, stop)
nmrChain.renumberNmrResidues(offSet, start, stop)

see a previous thread:

Change numbering in Chain/Sequence

Hi! When you create a chain in the program, you are able to add the molecule name, type, sequence, and the number that the sequence begins at. Once you have created the numbering, is there a way to go back and change this information?  For example, I create a protein to start at number 1 in the sequence. After a while, I need to fix the number so that the protein begins at number 20, not number 1. Just wondering if this edit is available in V3. Thank you! Domarin
