Hi,
The error message tries to make clear that genion can only replace
water molecules in an index group without gaps. It has to be
continuous. So the point that was made earlier on the list was that
the water molecules should be deleted in the .gro file. Alternatively,
they can also be moved to the beginning of the end of the solvent
section and from the (renumbered) resulting file an index file can be
constructed.
Hope it helps,
Tsjerk

you might have deleted just one atom of water molecule.
Ex: If you are using SPC water , you have to delete all 3 atoms in index
file.
Best way is to make changes in .gro file..
Renumber the resulting .gro file using genconf, make a new index file and
start running.
