Dear Gabriele,
The message for stopping is:
%%%%%%%%%%%
from checkallsym : error # 1
some of the original symmetry operations not satisfied
%%%%%%%%%%%%%%%
stopping.....
------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 0.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes. You may or may not see output from other processes, depending on exactly when Open MPI kills them.

  Dear Gabriele,

  Thank you very much for your reply.

  >Do you mean "Warning: symmetry operation #N not >allowed"? This is not an error, but simply a warning, 

  Yes, it is.

  >I doubt that this would cause the program to stop.

  But it stops a process in the mpi running. 

  > All.

  How can I constrain the system just ignore symmetry operations wrt the xoy plane (because the z coordinates change)?

  Bests,
  m.
