Dear abinitiers

I am doing an electronic structure calculation and
we are trying to track a problem with the electronic gap.
One way to deal with this problem it is to include the
scissor operator, which seems to me, it is include in
Abinit. But when I do the band structure calculation and
include the variable
sciss 0.1
nothing change in the band structure. I did check the input
variable description and it says that it will affect the
response part. Can somebody clarify to me how that is done? is it
possible to use the scissor operator just for the electronic
band structure? is it possible to use the scissor band structure
to calculate phonons?

Thanks in advance!!
