[Wien] A question regarding GGA+U method

[shamik chakrabarti]

Dear wien2k users,

                           If we use exchange correlation potential GGA and
modify case.inorb in such a way that nmod=1 and nsic=1 (SIC method, Anisimov
et al) then what we are using:

*GGA+U or self interaction corrected GGA?...or they are actually different
terminology of the same thing?*

I am asking this question because in a paper (PRB, vol. 74, 174431(2006)),
the authors told that they have used GGA+U once and then SIC-GGA....so
whether they are different?..if they are different then what is the
difference?...can you please suggest some reference...

Any response will be very helpful for us. Thanks in advance.

with best regards,
