about [r,Vnl]

Dear users
I get this "WARNING" when I run the yambo input.
WARNING] [r,Vnl^pseudo] not included in the position and speed dipoles.
doesn't this affect the result?
and how to include it?

Dear Maymoun,

yes, it can affect the oscillator strength values, but it is system dependent and in soma cases it can be neglected saving computational time.
It should be included by default, what kind of algorithms are you using to calculate dipoles (DipApproach)?

Best,
Daniele
