This means the MEP computation did not finish as expected, or the format of the
QM output is not the one expected...

1st this route line is not the one generated by R.E.D... ???

You modified something in the R.E.D. code, I guess... Why ?

Please use the unmodified version of R.E.D.-II and I guess it should work.
In particular, the QM calculations are done in 2 steps (i) geom opt. & (ii) MEP
computation (as it was recommended in the AMBER web site...)

>From what I understand the 2 steps are done in the same job in the input you
use...

Regards, Francois

PS Try the R.E.D. tutorials to better understand these 2 steps...
