Hi William,
Just wanted to bring this back to the VMD thread in case others had the
same thoughts you did.
I understand this isn't exactly what you are looking for, I just
copy-pasted a script I have for rmsd calculations, but this is a
generalizable method.
I recommend going over the Tcl scripting tutorial from www.ks.uiuc.edu
<https://www.ks.uiuc.edu/Training/Tutorials/> to get a basic foundation to
work with, and then revisit the script I have provided. You need to
automate the loading of your .pdb files (done in my script), and perform
atom-selections, which should be a simple addition.
