Dear H. Lee, I apologize for the late response. I was away from this project due to some unforeseen problems, but now I've fully returned to it. I put all the f90 files involved in the error report into the Dropbox folder [https://www.dropbox.com/sh/gdpmevzdd9ctsse/AAD1zxoZlBw2cEXVZG6KwDUpa] in the ...

Dear H. Lee, I believe I managed to run the code with debugging turned on, and here is the error message I received: forrtl: severe (408): fort: (3): Subscript #2 of the array G has value 0 which is less than the lower bound of 1 Image PC Routine Line Source epw.x 00000000015F8F5F Unknown Unknown Un...

Dear H. Lee, Thank you very much for your comments. Indeed, the problematic file seems to be written to disk where you point out in io_eliashberg.f90. I ran other calculations with temperatures above 100 K (as well as this calculation which had run properly up to 140 K), so the problem shouldn't be ...

Dear Hari, As you suggested, I attempted to restart this calculation from T = 140 K, but it seems that the same error occurred as soon as the calculation started (see epw2r.in and epw2r.out). I listed all the files that have "140" in their names, and none of them seem to be modified in the attempted...

Dear Hari, I apologize, it looks like I forgot to put some of the files in the folder. Indeed, epw2r.out is the output generated by epw2r.in, which is a restart calculation (imag_read = .true.). From what I understand, if I restart from 140 K, with all the files already present for 140 K, it will no...

Dear Hari, Thanks for your response! Shouldn't the code generate scf.imag_aniso_160.00 when I restart from 160 K (as in epw2r.in)? The problem seems to be that it writes the file name incorrectly as scf.imag_aniso_0***** and then has trouble reading it, as you point out. Why do you think I should re...

Dear H. Lee, I tried both of your suggestions (retrying with QE 6.7 and removing the nr1, nr2, nr3 variables) but the calculation fails at the exact same point. Because these are crucial calculations for me, I'm happy to work on debugging by modifying the code and printing extra things if you could ...

Hello, I'm attempting to run an anisotropic Migdal–Eliashberg calculation with EPW. When I use temperature values of 20 K, 40 K, 60 K ... 140 K, everything seems to be written correctly (see the scf.imag_aniso_* files for T = 140 K for reference). However, when I try to restart the calculation with ...

Dear H. Lee, Thank you for your response! I specified the nr variables in the scf calculation to fix an error I was receiving with EPW in QE-6.4.1, so you may be correct that it may not be needed in QE-6.6. I'd like to avoid changing the scf input at this stage, however, so I'm first going to try ru...

Hello, I am having trouble with an EPW run using the version that came with QE-6.6. I'm puzzled because I was able to complete this calculation with QE-6.4.1 earlier. Also, I ran the same calculation in a related system (the same system under a slightly different pressure) without a problem. The err...
