Actually, according to the nmoldyn-2 web site, it expects trajectories
to be in MMTK format. CHARMM, X-PLOR, NAMD and DLPOLY are handled
within the distribution, but a converter for AMBER trajectories is
said to be available separately. However, when clicking the link it
gave an Error 403, Access forbidden! message. It suggested to contact
the webmaster, however the email address was given as root.localhost;
not very helpful. I suspect just having an AMBER trajectory in netcdf
format would not be sufficient, else why have a specific converter
(and why handle the other MD programs individually?).

Is there a general purpose AMBER to MMTK converter available?
