Dear Eric,
I think it's a limitation that will need a deep look at the code to be
solved ... I suspect it won't be an easy task
as far as I am concerned only "H" are allowed to have 4 characters
(amber 7 manual p.25 top info about atom names)
On the other hand, the atom name has no relevance, it is chosen
arbitrarily, e.g. if you have three CL atoms call them CL1, CL2, CL3,
that's my suggestion (or any other 3-character name)
Regards,
Ivan.
