In R.E.D. you upload the Geometry optimization output(s) generated by
Gaussian or GAMESS to compute MEP(s) using Gaussian or GAMESS. Indeed,
the orientation of each minimum is controlled before MEP computation.
Thus, you use a QM program in (i) the Geomtry optimization step and in
(ii) the MEP computation step, and you cannot combine these two steps
into a single one.
