Error search for G=G1-G2 !!

[amolina]

Hello,

I am doing electron-phonon calculations.

I have a doubt when I do the nscf calculation to generate the k-point list where I will apply the el-ph correction.

Once I use p2y and I have create the SAVE directory, if I run yambo I get the following error:
[ERROR] STOP signal received while in :[03] Transferred momenta grid
[ERROR] Error search for G=G1-G2 !!

I have discovered that if I do yambo -i -V all and I set the following variables as follows:
% QptCoord # [KPT] [iku] Q-points coordinates (compatibility)
0 | 0 | 0 |
%

then yambo initializes the files correctly but I am not sure if I really understand what I have done...

Has anyone had a similar issue?

Cheers,

Alejandro.
