The attached file contains 7*7 supercell of graphene. You can directly import it into Materials Studio.

Monisha Rastogi

A 3*3 supercell just indicates that it is having 3 rings in X and Y direction.

http://www.nature.com/srep/2014/140901/srep06256/fig_tab/srep06256_F1.html

You can see a 7*7 supercell of graphene, given as figure b in the provided link. I think you can correlate now.
