[Pw_forum] Another problem with bands.x "reading band namelist"

[Imam Setiawan]

Dear PW_forum members,
I run into an error that seems to be already discussed in this forum. This is about "reading band namelist" error when trying to run bands.x. I have already tried solutions suggested in the other posts such as making the prefix and outdir the same as the pw.x's input files but it is not solved. Since all questions related to this problem that i have found pertain earlier version of QE (I used QE 6.0), could it be version-related problem?My input for bands.x is the following
&bands
   outdir = './work/',
   prefix='C_hexa_scf',
   filband='C_hexa_band.out',
   lsym=.true.
/
and the error I got is

Use "bands.x -i input-file", not "bands.x < input-file"; check that there
are no funny characters in the file and that all quotes are quotes and not
something else

Dear Paolo,
I have even retyped the input for bands.x with the correct quote (') and also used "~/qe-6.0/bin/bands.x -i C_hexa_band.in" to run it but it's still not successful with the same error message. I use the full path for calling bands.x instead of only "bands.x" because if I did that, for some reason it's bands 5.0 that is running. In this case the program seems to be waiting for input which I don't know what to type. It's what is showing when I used "bands.x -i C_hexa_band.in"

     Parallel version (MPI), running on     1 processors

In that state the terminal idles and nothing happened even if I typed anything, until I aborted it by Ctrl+C. I also tried moving outdir in all input files to the current folder just to see if something changes but it was also to no avail.

Best regards,Wahyutama
