[Wien] confusion with GGA+U and mbj

[shamik chakrabarti]

Dear Wien2k users,

                           If simulation of a material is to run with GGA+U
to get an approximate band gap, then *whether GGA+U or GGA* has to run as a
first step for running mbj?

As user guide says that we have to run a normal SCF prior to mbj, my
confusion is whether the normal SCF is to run with GGA or GGA+U if U is
mandatory for the material.

Looking forward to your response in this regard.

with regards,
