Can we combine HSE06/Wannier band calculations with Optical property computations?

Hi
i am generally do separate runs for (i) HSE06/Wannier band structure calculations and (2) Optical properties/Spectrum with HSE06 tags.
I wonder if we can combine these two in a single run.
Can anyone suggest if it is possible and if so, what specific tags needed, or precautions?
Regards

Hi,

For which reason you would like to combine band-structure and optics calculations in a single run? Have you tried with PBE?

Hi
thanks for the reply.
I presume, if i combine both HSE and Optics computations, we can save computation time.
in case of PBE, also i do Band and optics separately. but not combined so far.

Regards

You can get a (partial) answer by just trying yourself. To make this test fast choose PBE, a small system and small number of k-points.
