From my understanding, when numbering a PDB file, it is always numbered with the default scheme (imgt) and then stored automatically (as <inputname>-anarcii-imgt.pdb). This happens by simply running:
results = model.number(PDB_FILE_PATH)
Then, if you need a different scheme (in my case that's chothia) then you need to run:
model.to_scheme("chothia")
But this does not save a new PDB with the desired scheme, nor does the model export (to my understanding) any functionality to store a fresh PDB with the new numbering. Can you help me figure that out?
