Hi, Erik was too lazy to document this, I now added it to the manual. Type 4 is identical to type 1, it is only there to distinguish improper from proper dihedrals. Type 9 is identical to type 1, except that multiple entries in dihedraltypes will lead to multiple functions on one dihedral.

I noticed that proper dih are not converted to RB anymore (which's great for understanding) and to accomplish that apparently 2 new funct were added to the gmx code, namely 4 and 9. Needless to say that I couldn't find anything about funct 4 and 9 in the current gmx manual. I would appreciate more information about it. Among other things I would like to know, e.g., what funct 4 would have different from funct 1, since in the seminal work of Sorin, amber impr. dih are treated as prop. dih in gromacs.
