I was not originally aware that this could be caused by blank lines (because there are no blank lines at the end of the input files). I've tried skipping blank lines as suggested above, but this has not remedied the error. Currently, the error currently only occurs when the script attempts to process past the final line of the input. I can't figure out why it's attempting to do this in the first place.
