This is a bug/missing feature in the sense that there are GROMOS atom
types hardcoded in the program. I will have a look, but it should be
quite easy to fix for yourself if you update t_cmTAble all the way up in
the file. If you look closely you'll see that all the H entries are
dientical etc. If you have other atom types then please try to find the
correspoonding scattering factors..
