Error with geometry optimization of rGO

[hsuya]

I am trying to perform the geometry optimization of rGO however I am getting an error "No Pair Potential found" . Please find the script and error file in the attachment.

See https://docs.quantumatk.com/manual/SE.html

In the current version of QuantumATK, only the DFTB and Hotbit parameter sets contain a repulsive pair potential term, and only these methods can be used for geometry optimizations.
