Cluster Independent Annotation

CIA (Cluster Independent Annotation)

CIA (Cluster Independent Annotation) is a cutting-edge computational tool designed to accurately classify cells in scRNA-seq datasets using gene signatures. This tool operates without the need for a fully annotated reference dataset or complex machine learning processes, providing a highly user-friendly and practical solution for cell type annotation.

Description

CIA synthesizes the information of each signature expression into a single score value for each cell. By comparing these score values, CIA assigns labels to each cell based on the top-scored signature. CIA can filter scores by their distribution or significance, allowing comparison of genesets with lengths spanning tens to thousands of genes.

CIA is implemented in both R and Python, making it compatible with all major single-cell analysis tools like SingleCellExperiment, Seurat, and Scanpy. This dual compatibility ensures seamless integration into existing workflows.

Key Features

• Automatic Annotation: Accurately labels cell types in scRNA-seq datasets based on gene signatures.

• Clustering-Free: Operates independently of clustering steps, enabling flexible and rapid data exploration.

• Multi-Language Support: Available in both R and Python to suit diverse user preferences.

• Compatibility: Integrates with popular single-cell data formats (AnnData, SingleCellExperiment, SeuratObject).

• Statistical Analysis: Offers functions for evaluating the quality of signatures and classification performance.

• Documentation and Tutorials: Comprehensive guides to facilitate easy adoption and integration into existing workflows.
