Interpolation band error

Dear all,
When I completed the gw calculation and got the o.qp file, then I used ypp to interpolate the band and there was an error, so that there was no correct output, nor any error message.

Thank you in advance for your help!

Dear Sunxl,

to inspect the problem, you should post your input and complete report/log files.
You can also use the yambopy platform: here a tutorial for bands interpolation:

Best,
