Dear all,
         I am trying to calculate electron-phonon coupling strangth,anisotropic 
Elishberg spectral function , anisotrotic superconducting gap* using EPW as 
instructed from the site given below
http://epw.org.uk/Documentation/TutorialI am trying to run EPW on MgB2. I shall 
be highly obliged if anyone help me to find my error. I have calculated using 
the following steps:1.to run qe:mpirun -np 52 ../../../../bin/pw.x < scf.in > 
scf.out
mpirun -np 52 ../../../../bin/pw.x < fit.in > fit.out
mpirun -np 10 ../../../../bin/ph.x < ph.in > ph.out
mpirun -np 10 ../../../../bin/q2r.x < q2r.in > q2r.outmpirun -np 10 
../../../../bin/matdyn.x < matdyn.in > matdyn.outmpirun -np 1 
../../../../bin/lambda.x < lambda.in > lambda.outpython3 pp.py2.to run 
EPW:mpirun -np 4 ../../../../bin/pw.x < scf.in > scf.out
mpirun -np 4 ../../../../bin/pw.x -npool 52 < nscf.in > nscf.out
mpirun -np 4 ../../../../bin/epw.x -npool 52 < epw.in > epw.outIt is showing 
error :Program EPW v.5.5 starts on  8May2023 at 11:23:30
