Arpeggio gives "selection empty" or error for residue with no side-chain about arpeggio HOT 3 OPEN

Hi Harry,
I added the chain with a script and there was no issue. I do have to say that adding '//' does not seem to work when you don't have a chain.
Kind regards,

Hi Maria,

-s //24/ should work, and should select every residue numbered 24, so this may be a bug.

If you're able to share your PDB, please attach it to this issue, if not I can make some test data. I'll take a look when I have a chance.

Hi Harry,
I had to add a B chain for it to be recognised. Here is the link to get the pdb file https://gpcrdb.org/structure/homology_models/cnr2_human_intermediate. Even after deleting the first two lines of the pdb file, the same error appeared.
Kind regards,
