Worm-align and Worm_CP, Two Open-Source Pipelines for Straightening and Quantification of Fluorescence Image Data Obtained from Caenorhabditis elegans

Overview

This study introduces Worm-align, an open-source FIJI-based workflow designed for aligning and straightening Caenorhabditis elegans (C. elegans) samples. The workflow facilitates the analysis of fluorescence intensity through the Worm_CP pipeline and is applicable for quantifying heat-shock induced expression and lipid droplet imaging.
