Formatting problem in o.qp file

Concerns issues with computing quasiparticle corrections to the DFT eigenvalues - i.e., the self-energy within the GW approximation (-g n), or considering the Hartree-Fock exchange only (-x)

Formatting problem in o.qp file

Post by leoteo » Tue Apr 22, 2014 9:43 am

Dear all,

we are performing a GW calculation on a larger spin-polarized system using yambo Version 3.4.1 Revision 3187. The calculation seems to run fine and also the quasiparticle energies reported in the r_ file seem reasonable.
The o.qp file, however, shows some formatting problems: on some lines there are stars for the Spin_Pol and some lines are not properly indented (see excerpt below).

Code: Select all

Which lines are affected doesn't seem to be connected with the particular level, since in another run different lines were affected.
Has this been observed before? It might have to do with the size of the calculation. I hope this is indeed just a formatting problem and does not indicate problems in the calculation(?).

Leopold

Dear Leo,
thanks for reporting, we will check it.
It looks me a formatting problem, and should not indicate problem in the calculation, as the detailed output in the report file does look to behave well.
Best,
