cNMF-SNS: powerful factorization-based multi-omics integration toolkit

cNMF-SNS (consensus Non-negative Matrix Factorization Solution Network Space) is a Python package enabling integration of bulk, single-cell, and spatial expression data between and within datasets. cNMF provides a robust, unsupervised deconvolution of each dataset into gene expression programs (GEPs). Network-based integration of GEPs enables flexible integration of many datasets across assays (eg. Protein, RNA-Seq) and patient cohorts.

Communities with GEPs from multiple datasets can be annotated with dataset-specific annotations to facilitate interpretation.

⚡Main Features

Here are just a few of the things that cNMF-SNS does well:

• Integration of expression data does not require subsetting features/genes to a shared or 'overdispersed' subset
• Ideal for incremental integration (adding datasets one at a time) since deconvolution is performed independently on each dataset generating invariant GEPs
• Does not assume the same level of sparsity/depth (single-cell, bulk)
• Identifies interpretable, additive non-negative gene expression programs
• Two interfaces: command-line interface for rapid data exploration and python interface for extensibility and flexibility
