I have a similar error on MacOS Coot 0.8.9.3 EL, for DNA mutating.

Error: cannot find the standard residue for "Tr"

(1) using GUI "simple mutate" to mutate it to "T" on a DNA mol
(2) running python script "mutate_nucleotide_range(0,"C", 1, 2, "CT")"

I was also reading the other old posts about mutating DNA bases. However,
it would work for "U" but not "T".

Is there another version that I should try? Any inputs are warmly welcomed

Thanks again!
Ming
