This warning/behavior is expected. By default cpptraj attempts to
assign parameters for every residue; parameters are only skipped if
not all atoms for that residue parameter set are selected. This
probably could be made more efficient.
I would say as a first try just use the default parameters and see if
the residue recognition problem goes away; that will give us a good
starting point. Also, if you run with 'debug actions 1' set prior to
your jcoupling command the entire list of loaded parameters will be
written to STDOUT; you can check that to see if anything looks off. If
you're still having trouble you can send me the Karplus.txt file you
made and I can see if I can get the same behavior.
