Dear I was wondering if there is a way to represent non-canonical (otherwise known as xenobiotic) nucleic acids through UCSF Chimera (specifically, not ChimeraX .. haven't made the jump yet). I've looked through your documentation on the `nucleotides` section but was not able to find something along those lines. My PI told me it was possible, but I can't seem to find it. My apologies if I should be looking for this function elsewhere, but I thought it'd be easier to just ask. Many thanks in advance! Kind regards, Met vriendelijke groeten, Cordialement, ______________________ Rihon Jérôme jerome.rihon@kuleuven.be | +32 16 32 53 57 PhD researcher @Rega Institute for Medical Research | Laboratory of Medicinal Chemistry | Computational Research Herestraat 49 - box 1041, 3000 Leuven
