Everything is working fine until I try to run the GROMPP program with the *.gro and *.top files I got from GENBOX (spc-water, cubic box, mdp like in the manual). The error is different numbers of coordinates in the two files. What to do??? I re-run the whole cascade several times, everytime ending up with this error.

Some atoms in your gro are probably not listed in the topology. So check 
the number of water molecules, ions, etc and comare with your topology.

To count the number of water molecules, use, e.g.

grep SOL xxx.gro | grep -c OW

Good luck, jochen
