Hello,

I noticed that when I run epw.x with fermi_plot = .true., it will print out .cube files and a fs.bxsf file.

When I run epw.x again, these files are overwritten with (apparent) nonsense. Is this expected behaviour as it is not recomputing something on the restart?

I notice if I delete restart.fmt and run epw again, it will print out correct Fermi surface files.

Best,

Lewis

Hi Lewis,

Thank you for letting us know. Yes, you are right, there is something wrong going on during the restart. I will fix this as soon as possible.

Best,
Hari
