What problem does it solve?
PathML addresses the complexity of computational pathology workflows by providing an end-to-end toolkit that unifies loading, preprocessing, graph construction, ML model training, and multiparametric imaging analysis for whole-slide images and related data.
Core Features & Use Cases
- Image loading across 160+ proprietary formats with unified interfaces and slide classes
- Modular preprocessing pipelines including stain normalization, tissue/nucleus detection, and QC transforms
- Graph construction to model cellular/tissue relationships for graph neural networks
- Built-in deep learning models (HoVer-Net, HACTNet) with training, evaluation, and ONNX export
- Multiparametric imaging support (CODEX, Vectra, MERFISH) for per-cell marker quantification
- Data management using HDF5 storage, tile management, and distributed processing
Quick Start
Install PathML, load a slide with SlideData, generate tiles, apply a preprocessing pipeline, and save the results to an HDF5 file.
