[chimerax-users] Where is the renumber sequence tool in ChimeraX?

[Phan, Isabelle]

The sequence of my structure  includes  a tag and I want to renumber from -7 so that the first residue is the start Met. I tried the old chimera command resrenumber = FAIL. I googled and searched the docs, read the list of commands one by one, and still could not figure it out.

The API has a renumber_sequence() function but I don't understand the description (what’s "the given residues”? The chain?) and was unable to find an example on how to call this from the interface. I opened the python shell and typed:

from chimerax.core.commands import run
run(renumber_residues('#1/A:*', -7))
# FAIL

Sorry if this is trivial, I am still completely baffled by ChimeraX despite using it for years.

Thanks,

Isabelle
