So far, R.E.D.-III only recognizes geometry optimization outputs
generated from the Gaussian (94, 98, 03), GAMESS-US or PC-GAMESS

Using those programs, this "Invalid optimization OUTPUT" can have
three origins:

-1 The QM job generated is not valid. It did not finish correctly:
check the following words in the Gaussian/GAMESS output:

Author names
Stationary point found
Standard orientation
Normal termination of Gaussian => Correct job

Author names

-2 The atom order in the .p2n file is not the same than that observed
in the "Standard orientation" (after the "Stationary point found"
words) [Gaussian], or after the "EQUILIBRIUM GEOMETRY LOCATED" words
=> rebuild your p2n file according to the atom order found in the QM output.

-3 You have a frequency job in the Gaussian output. In this case, just
remove this 'second' QM JOB1b (because of the "Freq" keyword):

"JOB1" for gaussian with such a route "Opt=Tight Freq"

"JOB1a" geometry optimization
Stationary point found
Standard orientation
Normal termination of Gaussian
"JOB1b" frequency calculation |
  ... |
Standard orientation | removed this part
  ... | with a text editor
Normal termination of Gaussian | from the ouput

In this third case, see ; In the
section "-4", it is written:

" Finally, the frequency job available in the Gaussian output has to
be removed from the QM output (R.E.D. II and III only recognize
optimization output, and generates an error message if an optimization
job followed by frequency calculations is used as input; this might be
changed in R.E.D. IV)."
