[gmx-users] pdb2gmx - .top missing values

Well, I got to the stage today (having sorted out the force field, residues 
etc) to start to use the .top file generated by pdb2gmx using the new 
residues I had defined.  However, grompp comes up with a warning that there 
are no default angles suppled in .top, and has to use zeros.  That comes up 
10 times then it halts, since 10 warnings is where it is meant to.

Therefore, from this I assume that pdb2gmx should be putting the bond 
details, not just which atoms are involved, into the .top file.

Are there any suggestions on why it may be the case that it isn't putting 
those into the .top?
