+framework for the integration of multi-omic data sets in an unsupervised
+fashion.  Intuitively, MOFA can be viewed as a versatile and statistically
+rigorous generalization of principal component analysis to multi-omics data.
+Given several data matrices with measurements of multiple -omics data types on
+the same or on overlapping sets of samples, MOFA infers an interpretable
+low-dimensional representation in terms of a few latent factors.  These learnt
+factors represent the driving sources of variation across data modalities,
+thus facilitating the identification of cellular states or disease
+subgroups.")
