Inconsistent data error

Dear experts and users,

I have run into a problem during an EPW calculation:

Code: Select all

    ===================================================================
     irreducible q point #    1
     ===================================================================

     Symmetries of small group of q: 12
          in addition sym. q -> -q+G:

     Number of q in the star =    1
     List of q in the star:
          1   0.000000000   0.000000000   0.000000000
   22152.6523050249        87453.0750325916

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine readmat_shuffle2 (1):
     inconsistent data
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

     stopping ...


From the other posts regarding this problem, I understood that it can only be related to discrepancies between scf/nscf runs before epw and phonon run. I copied my scf file from the phonon folder to the epw folder so there could not be a mistake. The only tricky thing I did is that I calculated phonons in parallel in several separate folders (several q points per folder) so I had to modify pp.py script so it collects all the files in the 'save' folder.
It can be that I did something wrong when modified the script.

Could this error message be related to some erroneous arrangement of files in the 'save' folder?
Otherwise, what else could be a reason? What can I check?

Thank you.
Best regards, Mikhail

Ok, I messed up the masses, and that is what caused the problem.
Sorry, my bad.
