Hey, Diana - I believe these acetonitrile holes are not a problem. Just perform an equilibration run in the NPT ensemble and they will disappear. The more tricky way is to adjust VDW radii in vdwradii.dat before using genbox.
By the way, what force field model of acetonitrile do you use here? Some time ago I uploaded a few simulation boxes with acetonitrile onto the gromacs official website, hopefully they can be also useful for you to start. Good luck! Dr. Vitaly V.
