The routine to do so is clear to me but I am getting energy 20 kcal/mol higher than the reported values. I used the highest basis set available in CP2K with the vdW corrected PBE. The script I am using for geometry optimization is given at the end. The optimized geometries of the individual and supra molecules I get using these inputs are very much similar to the ones given by other workers. It is just the high binding energy that I am not getting correct even after correcting for BSSE. I cannot figure out what the reason could be..
