Dear Kajal Jindal<br>
It is only a matter of labels... The first implementation was an LDA+U one, and the input key was named lda_plus_U after that. But if your underlying<br>
functional is a GGA one, e.g., PBE, you are performing GGA+U (or DFT+U, that is a generalization) even if the input key is still called (for laziness<br>
or compatibility, I don't know... :-) ) lda_plus_U.<br>
