Yes, this works! Thanks alot.
I only wounder to know should I delete
[ exclusions ] from the itp of my X-ray water or not ? This directive is
linked with the [settles] by the if expression so I've replaced it too.

> It's clear now. As I understtod the [moleculetype] of the restricted
molecule must be in FIRST place in my topol.top file but in that file the
PROTEIN at first place instead. How I could make this changing in my
multi-topology file ? I've tried to place
; Include X-ray water topology
; Include Position restraint for XW
at the begining of the topol.top file. But the error during grompt was the
same about wrong atom order :(
