Hi,
Someone forgot to edit topsort.c when added a new dihedral type.
I fixed it for 4.5.2.
The fix is an addition of one line, see below.

Message body
I started a small 2 nucleic acid system for FEP testing. As well as turning
on fep, I set RNA_Chain_A as the couple-moltype. I also set couple-lambda0 and
couple-lambda1 to vdw-q and none respectively. I then began a "steep" mdrun and
got this error:
Program mdrun, VERSION 4.5
Source code file: topsort.c, line: 112
Fatal error:
Function type Improper Dih. not implemented in ip_pert
For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors
I have searched for this on google and found nothing. Do I need an Improper
Dihedral section in my top/itp file? I have ran this same system with fep off
and it runs perfectly.
Any help is much appreciated.
