delete_atoms command

Dear all,

When I am not using delete_atoms command everything works fine.
But when I am using that “delete_atoms group cy mol yes” I get the following error:

ERROR on proc 0: Dihedral atoms 262 260 261 255 missing on proc 0 at step 0

Cut-off for lj and coulombic interaction is so large (15A). As well as dihedral has not blown apart because before delete “group cy” there is no error.

Thanks a lot
