ypp PPs rotation

[burkzdemir]

Dear Yambo developers,

I runned GW calculation and then I wanted to obtain GW bands with ypp -y -s b. However my calculation stops at the step " <20s> P0001: PPs rotation | | [000%] --(E) --(X)". What could be the problem?

Dear Burak,
this should be done in two steps:
> ypp -y
edit the generated input file to remove the time-reversal symmetry and run ypp.
This will create a new directory were the symmetries are removed.
Enter in the directory and run the yambo setup (yambo -i )
and next the band interpolation (ypp -s b).

I'm not sure if it still needed to remove the TR symmetry.
If you still encounter problems, please post here again by attaching your input files.

Best,
Daniele

Thank you! It worked.
