Mike,

You should 1st try the test cases provided in the R.E.D. tools distribution.

Here, this means the optimization step did not finish correctly.
Check the JOB1-gam_m1-1.log file...

JOB1-gam_m1-1.log should be in the working directory with the RED code
& the P2N file.

If you do not find JOB1-gam_m1-1.log this might simply mean it was not
generated ;-)

If I look below, you use Cygwin. right ? I never used R.E.D. on cygwin.
We have only Linux machines in the lab.

R.E.D.-III.2 works now on MacOS as well thanks to T. Patko.

I would first run PC-GAMESS without R.E.D. to see if PC-GAMESS works:
Using the input "JOB1-gam_m1-1.inp" (generated by R.E.D.) do you get
the PC-GAMESS output JOB1-gam_m1-1.log ?

=> You might also decide to use R.E.D. setting
$OPT_Calc = "Off" & $MEPCHR_Calc = "On"
In this case, you have to provide the QM geometry optimization as
input for R.E.D. Its name has to be Mol_red1.log (or Mol_red$n.log of
$n molecules involved in the charge derivation).
