README.md

Four Cell Script

Two scripts:

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

Analysis Steps

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