This repo contains a simple package that simplifies the access to the silhouette files, as well as a script to calculate, for each contour, the sum of all the pixel values of each channel using the source TIFF file.
This package is provided as-is. Clone it and adapt it to your needs!
A python environment is recommended (conda could work as well). In it, install the requirements and this package:
$ pip install -r requirements.txt
$ pip install git+https://github.com/amarallab/silhouette-extract
