[kazempoor at ph.iut.ac.ir]

Dear ALL
For running pw4gww on wannier input file I see the running is crashed in mideway.

the input file is in the following:
 &inputpw4gww
    prefix='tio2-perfect'
    outdir='/p5/batch/kazempou/tmp'
    lwannier=.true.,
    cutoff_wpr_vc=0.02d0
    cutoff_products=0.01d0
    cutoff_polarization=0.01d0
    num_nbnd_first =310
    num_nbndv=288
    num_nbnds=300
    l_truncated_coulomb=.false.
    remainder=-1
    restart_gww=0
    numw_prod=1
    n_gauss=79
    omega_gauss=20.d0
    tau_gauss=10.d0
    l_zero=.true.
    l_wing=.true.
    cprim_first=1
    cprim_last=300
    l_polarization_analysis=.true.

and in the end of output file I faced with this error:
