A factor analysis framework for unsupervised integration of multi-omics datasets.
MOFA (Multi-Omics Factor Analysis) is a computational framework for integrating multiple types of omics data in an unsupervised manner. It uses factor analysis to identify latent factors that capture shared sources of variation across different molecular measurements, helping researchers uncover biological patterns and relationships. The tool addresses the challenge of analyzing complex, multi-modal biological datasets where individual analyses might miss cross-dataset correlations.
Bioinformaticians, computational biologists, and researchers working with multi-omics data who need to integrate genomics, transcriptomics, proteomics, or epigenomics datasets to discover underlying biological processes.
MOFA provides a statistically rigorous, model-based approach to multi-omics integration that prioritizes interpretability and flexibility. Unlike methods that require prior biological knowledge or supervised signals, it operates unsupervised and can handle diverse data types within a unified framework.
