[Pw_forum] error running module pw4gww.x

[alberto]

Hi,
running module pw4gww.x, I obtain this error message

'Error in routine ggen (589): too many g-vectors
​'


this is my setting for the run


&inputpw4gww
prefix ='SnI4_Cs_SR'
num_nbndv(1)=50
num_nbnds=60
l_truncated_coulomb=.false.
numw_prod=2000
pmat_cutoff=3.d0
outdir = './tmp_qe'
s_self_lanczos=1.d-13
nsteps_lanczos_self=90
l_big_system=.true.
s_first_state=50
s_last_state=51
l_verbose=.true.



and this is my geometry, and scf, nscf, head, and nscf (in gamma point),
converged correctly
