Error in routine epw_readin (1): reading input file

dear EPW developer

during I run epw.x, an error occurred while reading the input file there is an error reported:

Hi yq_zhao,

The input file looks fine. I even double checked with epw-v5.3.1, it runs fine. I assume something is not correct in your scf and nscf calculation.
Could you tell us which version of the code are you using and provide your scf.in and nscf.in files?

Best,
Hari Paudyal
