ypp input flag descriptions?

[soumyadeepghosh35]

Dear All,
I am trying to compute GW band interpolation of FeSe/BaFe2As2 using Wannier-90/YAMBO. An example is demonstrated in "wannier90-3.0.0/examples/example23". But I am unable to get descriptions of input flags used in ypp. It is available for yambo.

Can anyone please share the link where I get ypp input flag description?

with many thanks and best regards
Soumyadeep

Dear Soumyadeep,
you can have a look to this thread and the link indicated in the post for a tutorial on band interpolation using Wannier90. Maybe Antimo can help you on that.

Best,
Daniele

Dear Soumyadeep,

the only 2 relevant input flags for ypp are the ones reported in W90 example 23, I copy them here below for convenience:

Code: Select all

wannier                      # [R] Wannier 90 I/O
Seed= "silicon"                     # Seed name

"wannier" triggers the yambo/wannier90 interface, while "Seed" is just the seed name you have in wannier90.

I hope it's all clear now, please let us know if otherwise.
As a note, I will coordinate with the other yambo developers to update/improve the ypp documentation on input flags.

Best,
Antimo

Dear All,
I am getting following error when running gw2wannier-90,

I do not understand the problem? FeSe.gw.eig is also blank.
