[QE-users] Using Bands.x for quantum espresso version 6.3

[Iftikhar Ahmad Niaz]

 Hi all

I'm trying to generate band diagram plot with QE version 6.3. Scf run and
Bands run works fine in parallel version. However, after the bands run,
when I try to generate .dat file using bands.x, I get error listed below. I
also found that now the wavefunctions are written in the directory
prefix.save not like previous versions where it was used to be prefix.save/K
FYI: I'm using same parallel scheme (no of cores, k point division etc.)
for scf, bands run for pw.x and bands.x and my wf_collect is set to .true.

Error message:

forrtl: severe (24): end-of-file during read, unit 99, file
/../out/prefix.save/wfc1.dat

I would highly appreciate if someone could share their experience in
