Hello everyone.  
I’m a beginner in the Abinit program.  
I would like an input file for calculating band structures according to the TB-mBJ correction for two-dimensional materials.  
Regards.

Dear Khadir,

Welcome to the Abinit forum.  
Since you are a beginner to Abinit, I first recommend getting familiar to the environment with the set of very detailed and instructive tutorials: [Basic tutorials](https://docs.abinit.org/tutorial/base1/)

If you already familiarized yourself with the abinit environment, I recommend having a look at the way metagga functionals are used in abinit in the [ixc](https://docs.abinit.org/variables/basic/#ixc) keyword (via the linked libXC library).

To generate an input file, I recommend using the graphical user interface available on the abinit page: [Input File Generator](https://gui.abinit.org/input_generator)

Good luck!  
Bogdan
