Dear developers,
I run yambo -o b -k sex -y d to do bse calculations
but there are not some parameters which included in the documentation
like KfnQP_E or KfnQP_Wv
etc. Is it important to write them in the generated input file by the
yambo -o b -k sex -y d ???

Dear S. Atei,
they are variables that appear if you ask for increasing verbosity.
e.g: yambo -o b -k sex -y d -V qp
as reported in the documentation
Here you can find a list of the verbosity level. Using -V all you will activate all the variables.
If they are important, it depends what you want to do. KfnQP_E has to be set if you are planning to add the QP corrections using a scissor operator, otherwise if you want to read them from a previous GW calculation you need to use KfnQPdb. KfnQP_Wv it is not used in BSE calculation.

Best,
