Command to execute, parallelization
***********************************

Normally you would run:

   "$AMSBIN/reactions_discovery" < input_file.in > output_file.out

This will **run in parallel** and use as many cores as are available
on the system or allocation.

You can also explicitly set the number of cores with the "-n" flag.
For example, to run the "reactions_discovery" program **in serial**,
you would run:

   "$AMSBIN/reactions_discovery" -n 1 < input_file.in > output_file.out

Or you could also run Reactions Discovery in Python (PLAMS).
