Hi new developer When I run the EPW example for MgB2, I obtain two output files: `MgB2.α2f` and `MgB2.α2f_proj`. However, the `MgB2.a2f_proj` file only contains the mode-resolved Eliashberg spectral functions corresponding to the first smearing value in `MgB2.α2f`. How can I obtain the mode-resolved ...

Hi epw developer I am using the 5.8 version of epw to calculate superconducting temperature, and have some problems running epw.x. epw.x has completed the calculation of wannier90, and an error may be reported during the calculation of “irreducible q point” this is the error --- ...

Hi Shashi Thanks for your reply I followed your advice and modified froz_max. The Wannier Center expansion did shrink, but it was of limited help in resolving errors. I even modified the Froz window range to 0,1 eV near the Fermi level, and the resulting Wannier center extension is: MMN calculated ...

Dear developers, I am using the 5.8 version of epw to calculate superconducting temperature, andI have run through pw, ph and w90, but failed when calculating the electron-phonon matrix elements. The error message is listed as follows. Could you please tell me how to fix this problem? Thank you very ...

Hi Gyanu

I set 'nosym=.false.' in my nscf.in, Then you encounter the following error:

Error in routine epw_setup (1):
coarse k-mesh needs to be strictly positive in 1st BZ

Hi Roxana

I followed your advice and changed to the latest version of epw.x5.7 for recalculation. Unfortunately, the error still exists.

setting 'calculation = scf' is my input error, but in the calculation process was setting 'calculation=nscf'

Hi, epw user I am using the 5.6 version of epw to calculate superconducting temperature, and have some problems running epw.x for PbTaSe2. this is the error in epw.out : AMN k points = 576 in 24 pools 1 of 24 on ionode 2 of 24 on ionode 3 of 24 on ionode 4 of 24 on ionode 5 of 24 on ionode 6 of 24 ...

Hi H.Lee

The wout file has a total of 82691 lines. I put the file in the compressed package, please have a look
