Hi, I'm getting this error when trying to generate the SAVE folder with p2y. I'm performing a convergence test to get the optical spectrum, but I get this routine error with meshes from 42x42x1 K-points. Up to 30x30x1 I managed to generate the SAVE folder successfully. can anybody help me?

I'm trying to generate using q.e v.6.3 and YAMBO version 4.5.2.

Dear Renannarciso,

the problem you report is most probably a version clash.
Surely one can investigate further the problem, but since QE-6.3 is quite outdated now (3y old), as a first simple option I would consider moving to a more recent version of QE.
Similarly, you probably should consider using the latest yambo 4.5.x (which is 4.5.3), or moving directly to yambo 5.0 (v5.0.3 as of today).

If for some reasons you really need to use the versions you mention, pls send an input file that we can use to reproduce the problem.

take care
Andrea
