[Pw_forum] Error in routine phq_readin (1): reading title

[Andrea Pedrielli]

Dear users,
I'm doing some GW calculation with Quantum Espresso, version 6.1. I
compiled the MPI version on a cluster, and I can successfully run pw.x
program for scf calculations. However when I go to run the head.x program I
obtain the error message " Error in routine phq_readin (1): reading
title"  reported
below.
The same error that I found with my system (graphene) I obtained also with
the example02 for silicon in Example/GWW/ directory.
I do not obtain this error when I run head.x for silicon example on my PC,
using the same MPI QE version.
Any idea?

Thanks in advance,

Andrea Pedrielli
