No useful output to stdout

You seem to be redirecting all of the output to a file -- I suggest we do not do this. Users can choose to redirect the output themselves, e.g.

python step_2_*.py > results.txt

or, to both see the output AND save it to a file:

python step2_*.py | tee -a results.txt

I think it is confusing to see no output other than "start" and 'finish" when you run the program

Or at least mention that detailed output will be going to the log file at {LOG LOCATION}
