# Four Cell Script

Two scripts:

1. Analyzes a calibration sheet on the plotter to generate a template.
2. Takes cells and inserts them into the template 4 at a time.


## Analysis Steps

1. Locate positions of 6 hole punches - normalize.py
2. Orient to square position - normalize.py
3. Find all 4 fiducials
4. Calculate their position relative to the hole punches
5. Create a template 
6. Use the template-filling script to recreate calibration page as a proof to be checked on a lightbox
