Area of Science:

Computational Biology
Neuroscience
Developmental Biology

Background:

Quantitative phenotyping of Caenorhabditis elegans is crucial but hindered by data extraction bottlenecks.
Traditional segmentation methods struggle with image variations (noise, overlap, illumination), requiring extensive manual effort or specialized equipment.

Purpose of the Study:

To introduce TWARDIS (Tools for Worm Automated Recognition & Dynamic Imaging System), an AI-powered Python suite to automate C. elegans image analysis.
To demonstrate TWARDIS's robustness and versatility across static, behavioral, and neural imaging modalities.

Main Methods:

Leveraged large foundation vision models (Segment Anything Models - SAM and SAM2) and a fine-tuned vision transformer classifier.
Developed a modular, Python-based analysis suite for automated segmentation and phenotyping.
Validated across static morphology, swimming/crawling behavior, and calcium imaging.

Main Results:

Achieved 0.999 correlation with manual segmentation for static morphology, resolving overlapping worms in noisy images.
Enabled high-definition postural analysis in low-resolution behavioral recordings without frame rejection.
Provided precise neural compartment segmentation and accurate head position extraction in calcium imaging data.

Conclusions:

TWARDIS effectively automates complex C. elegans image analysis, removing critical bottlenecks and tradeoffs.
The AI system enhances throughput and reduces bias in phenotyping across diverse research applications.
TWARDIS's modular and scalable design supports current accessibility and future advancements in C. elegans research.
