Unless you're trying to build sugar chains, you don't need to make building
blocks in the .rtp file. It is better to use .itp files for them. Also, it's
better not to use the gmx force field, but rather the GROMOS one, for which
there should be good sugar parameters available (by Roberto Lins).
And genbox doesn't use the .rtp file, it's only used by pdb2gmx. Genbox will
insert molecules from a structure file (gro, pdb).
