Area of Science:

Single-cell multimodal omics
Computational biology
Bioinformatics

Background:

Single-cell multimodal omics generates large datasets requiring sophisticated integration methods.
Diagonal integration offers flexibility but risks artificial alignments due to ambiguous cell mappings.
Existing methods lack diagnostics for spurious integrations in diagonal data integration.

Purpose of the Study:

To introduce SONATA, a novel diagnostic method for detecting artificial integrations in diagonal single-cell data integration.
To address the challenge of ambiguous cell-cell mappings leading to unreliable multimodal data integration.
To provide a tool that enhances the reliability and interpretability of single-cell multimodal data analysis.

Main Methods:

SONATA quantifies cell-cell ambiguity within the data manifold to identify ambiguous alignments.
The method acts as an add-on to existing diagonal integration pipelines.
Evaluated using simulated and real multimodal single-cell datasets.

Main Results:

Artificial integrations are widespread and overlooked in mainstream diagonal integration methods.
SONATA successfully distinguishes biologically meaningful integrations from spurious ones.
The diagnostic method provides actionable insights into potential integration failures.

Conclusions:

SONATA offers a robust framework for ensuring the reliability of multimodal single-cell data integration.
The tool safeguards against misleading integrations and improves data interpretability.
SONATA is crucial for accurate analysis of complex single-cell omics data.
