REAX/C short ranged linked list cell size info

Dear lammps users,

I am trying to study the effect of linked list size and qeq on the performance of NVE ensemble in lammps.

But for doing this I need to change the short ranged linked list cell size and qeq tolerance values.

I know how to change qeq tolerances, because that is an argument to qeq fix. But I do not know how to increase or decrease the linked list cell size in lammps. Is there a parameter in the code that controls it, or some command that can vary it.

I do not know how to do this and I do not want to change the code in any respect, as I do not understand how the reax/c flow of control is and how the code is implemented.

Please help!

Thanks,
Ankit
