ERROR in topology_generate_molecule

[Papy]

Hello,

I am a neophyte in CP2K simulation. When a lauch the simulation I have
this error :



*******************************************
 *** ERROR in topology_generate_molecule ***
 *******************************************

 *** CP2K requires molecules to be contiguous and we have detected a
non   ***
 *** contiguous one!! In particular a molecule defined from index
(     1) ***
 *** to (  8881) contains other molecules, not connected! Too late at

this ***

issue.
