[Pw_forum] Problem getting projections and .mmn file

[sudipta]

Dear all,
I am new to quantum espresso with wannier.
I have installed the program and then run all the example. Now I want to
calculate MLWF for FeO for that I have given the input as

# Wannier90 to get nnkp
cat > feo.win << EOF
#num_bands     = 20
num_wann        =  11
num_iter        = 20
wannier_plot    = true

wannier_plot_supercell =3
#bands_plot = true
begin kpoint_path
L 0.5 0.5 0.5 G 0.0 0.0 0.0
G 0.0 0.0 0.0 X 0.5 0.0 0.5
end kpoint_path

begin atoms_frac
 O1  0.25 0.25 0.25
 O1  0.75 0.75 0.75
 Fe1 0.0  0.0  0.0
 Fe2 0.5  0.5  0.5
end atoms_frac

begin projections
Fe1: d
O1: p
end projections

but it is showing following error:

--------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD

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.
