<p style="margin-top:0;margin-bottom:0">I am trying to mutate nucleotide residues in RNA using Chimera, and I've seen previous posts about using the "swapna" command. However, Chimera is giving the error message "Unrecognized command: swapna". Is there a
way for me to enable swapna for Chimera to recognize so that I may use it?</p>
