Hello, For RNA modelling I used to have a "user-defined-restraints.scm" script which allowed me to maintain proper base-paring geometry while I did real-space refinement and regularization. Unfortunately, my script doesn't seem to work on new coot versions; as I'm running the script the restrains tab opens, I'm able to select to nucleotides but then the real-space refine doesn't maintain proper base-pairing geometry (the latest coot version that it worked in was 0.7). Do you have an updated script for the newer versions of coot or can you command me another options for RNA helix refinement?
Thanks! Donna
