Bioinformatics
Computational Biology

Background:

Single-cell RNA sequencing (scRNA-seq) enables high-resolution cell-type composition analysis.
Identifying rare cell types is crucial but challenging with existing methods.
Current scRNA-seq analysis tools lack scalability for large datasets.

Purpose of the Study:

To introduce GiniClust3, an advanced software package for scRNA-seq data analysis.
To address the scalability limitations of existing rare cell type identification methods.
To provide a faster and more memory-efficient tool for dissecting cell populations.

Main Methods:

GiniClust3 is an extension of the GiniClust2 algorithm.
The software is designed for enhanced speed and memory efficiency.
Implementation within an open-source Python package facilitates accessibility.

Main Results:

GiniClust3 processes datasets exceeding one million cells in approximately 7 hours.
The tool robustly identifies both common and rare cell clusters.
Cell type mapping and perturbation analyses confirm GiniClust3's accuracy.

Conclusions:

GiniClust3 is a powerful and scalable tool for identifying cell populations in large scRNA-seq datasets.
The software effectively distinguishes both common and rare cell types.
GiniClust3 is available as an open-source Python package.
