[Chimera-users] Assigning nucleotide representation to non-canonical nucleotides

The slabs are drawn based on the presence of atom names that appear in standard purine and pyrimidine nucleotides. It might work for nonstandard ones that contain those atoms, but in general, if the base is different enough that it does not contain those atom names, the slab is not drawn.
I know that the Nucleotides tool can draw ladders, slabs, etc. for the standard bases + pseudouridine. If you try using it on other bases and it keeps showing sticks only, then my guess is no, it does not work for those.
Also, as far as I know, the base recognition in ChimeraX for drawing nucleotides is the same as in Chimera.
I hope this helps,
