Hey all,

I have an assignment for my biomedical programming class that requires us to calculate the instantaneous heart rate of a given input text file. My professor suggested using a technique called the "Threshold and Blank Algorithm." Could someone point me in the right direction to begin this project. I know how to begin (scanning the file with a while loop, etc.), it's just getting to the guts of the program I'm having trouble with.

Where can I begin?
