Subject: AMBER: problem with Thermodynamic Integration

I'm trying to run thermodynamic integration, and have followed the manual pretty much to the letter so far.
The only problem I've run into is that when I try to run

prun -n 2 sander -ng 2 -groupfile 0.tp3.TI.in

I get the error message:

>mdfil: Error unknown flag: -ng
>usage: sander [-O|A] -i mdin -o mdout -p prmtop -c inpcrd -r restrt
>[-ref refc -x mdcrd -v mdvel -e mden -idip inpdip -rdip rstdip -mdip mddip -ng numgroup -remlog remlog -rem [0|1|2] -inf mdinfo -radii radii]
>Consult the manual for additional options

It strikes me as odd that the flag is unknown, but also in the list of known flags... should they be in a specific order??

Regards,
