I believe this is not an existing ptraj capability. If so, unless
there is a non-Amber program that you could e.g. feed pairs of pdb
files to, I think you will need to do some programming to make that
happen. The tricky part would be if the two forms are not chemically
identical. In this case, you'd need to read in two prmtops and
just align/measure the parts that are the same.
