Hi, Christ,
I took a look at your gaussian output file. It does not contain the
identifier of "Standard orientation:" after the line that has the identifier
of "Optimization completed.". Therefore no coordinates are read in by
antechamber at all. If you use the gaussian input files generated by
antechamber, that identifier is always there. Anyway, I will fix the code to
handle this kinds of special cases.
Now you may simply fix this problem yourself by changing the first "Input
orientation:" after the line of " Optimization completed." to "Standard
orientation:" in the gaussin output file. That is to say:
change line 14892 to " Standard orientation:"
Best
