Dear H. Lee,

By assigning absolute path of the working directory to tmp_dir in readwfc subroutine, I am able to avoid this error.

Thanks for your time.

Regards,
Prasad

Dear H. Lee,

After completing the .epb file writing part, job is terminating from the queue with error msg:

The .epb files have been correctly written


Band disentanglement is used: nbndsub = 60
Use zone-centred Wigner-Seitz cells
Number of WS vectors for electrons 279
Number of WS vectors for phonons 19
Number of WS vectors for electron-phonon 19
Maximum number of cores for efficient parallelization 912
Results may improve by using use_ws == .TRUE.

Dear Prasad:

Before solving the current issue,
if you still encounter the failures in test-suite, you first should resolve them.
The success in test-suite is a minimal prerequisite for the production run.

Sincerely,

H. Lee
