The authors present a spectral manifold alignment and inference (SMAI) framework that enables principled and interpretable alignability testing and structure-preserving integration of single-cell data.
Kivonat
Single-cell data integration is crucial for understanding complex biological systems. Existing methods have limitations, but SMAI offers robust alignability testing, improves downstream analyses, and enhances interpretability by quantifying technical confounders.
Key points:
SMAI addresses limitations in existing single-cell data integration methods.
It provides a statistical test to assess alignability between datasets.
SMAI improves downstream analyses like identifying differentially expressed genes.
The method enhances interpretability by quantifying sources of technical confounders in single-cell data.
SMAI's performance was evaluated on diverse real and simulated benchmark datasets, outperforming popular alignment methods. It preserves within-data structures, removes unwanted variations effectively, and enhances reliability in differential expression analysis.
Statisztikák
"On a diverse range of real and simulated benchmark datasets, it outperforms commonly used alignment methods."
"For each task, we test for partial alignability between each pair of datasets."
"Recommended values for t are between 50 and 70 depending on the context."
