Hi all, I was wondering if anyone had any suggestions on how to rotate and translate a DNA-bound protein model one base pair at a time (essentially walking the protein down the double helix) so I can compare its interactions with another protein. My plan was to define a vector between the center of mass of each nucleotide pair to then move the DNA-bound protein one average pitch length using the move command and rotation using the turn command one nucleotide at a time. When I try to save these new models using "save pdf_filepath.pdb models #3 relModel #1" the DNA-bound protein is still in the original position - do I need to modify the save command or move the DNA-bound protein using different commands? Thanks for any help you can provide! Best, John
