Dear all

is there a method to restart Screening calculations or Sigma calculations from a previous run
that is not completed with the same input variables.

Thanks.

For the screening, there are ways to split the calculation into independent jobs.
Look at the variables nqptdm and qptdm. It allows you to compute the screening for each q-point individually, then you can merging them at the end with mrgscr. This procedure is more safe for very large calculations.
Also, if a screening calculation crashes, it may have produced a _SUS file. It's the susceptibility, which has to be inversed to give the screening. You can restart the run from that point, using irdsuscep.
