Dear Dr. Paolo,
I am ruing a case and got "fft order too large" error.
I tried with QE version 6.4.1 and 6.5 and error persists.
Then I found the this email where you supplied a patch (frac-patch.diffs).
may I ask you how to apply this patch?
Thank you very much.
Best Wishes,
Ms. Rekha

Very funny. I think I know why: it's a highly nonlocal effect of a small
change I recently did to get rid of an old and annoying problem with
fractional translations not commensurate with FFT grid. Apparently the code
found a fractional translation 1/13 and tried to make the FFT grid
commensurate with it. Please try the attached patch
