Harmonizing neuroimaging data across sites. Implementation of neurocombat using sklearn format

Project description


License: MIT Version PythonVersion

Implementation of Combat harmonization method in scikit-learn compatible format.

The Combat harmonization/normalization method uses an parametric empirical Bayes framework to robustly adjust data for site/batch effects. The scikit-learn compatible format was used to facilitates the use of this harmonization method in machine learning projects.

This repository is developed by Walter Hugo Lopez Pinaya at King's College London and community contributors.
