Machine learning and prediction

Mol2CCS

A research codebase for graph-neural-network prediction of ion-mobility collision cross sections from molecular structure, developed to evaluate model generalizability across chemical domains.

Platform-independentPython packageOpen source

Overview

Mol2CCS supplies graph-neural-network training and prediction code used to study CCS generalization across datasets. Models operate on molecular structures, adducts and optional three-dimensional coordinates, with prepared datasets and evaluation notebooks.

Scope and considerations

Designed for

  • A research codebase for graph-neural-network prediction of ion-mobility collision cross sections from molecular structure, developed to evaluate model generalizability across chemical domains.

Not designed for

  • Calibrating experimental mobility measurements or guaranteeing accurate CCS for chemical domains absent from model training.

Important requirements

  • The documented Python/Poetry environment, compatible molecular/adduct data and a trained model; reproducing the experiments additionally requires downloading and preparing the licensed METLIN-CCS/CCSBase datasets.

Considerations

  • Dataset splits, adduct definitions and structural domain affect evaluation. The repository is a research framework; do not assume a maintained universal pretrained prediction service.
