Hi Maria and Adam, I think it's not that complicated. You need "cartoon_ring_mode" for the residue selection. Example:
fetch 1rna, async=0 as cartoon select firstres, chain A & resi 1 set cartoon_ring_finder, 2 set cartoon_ring_mode, 2, firstres color blue color red, firstres extend 1 Hope that helps.
