RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

To provide guidance on selecting appropriate methods and discuss future directions.

Main Methods:

Systematic literature review of 32 published automated scRNA-seq analysis tools.
Comparative evaluation of method performance using key metrics (accuracy, F1-score, unlabeling rate, runtime).
Development of a free software package integrating the evaluated methods.

Main Results:

Performance metrics varied significantly across the 32 automated methods.
Specific method strengths and weaknesses were identified for different analytical scenarios.
Recommendations for method selection were formulated based on data characteristics and user needs.

Conclusions:

Automated methods significantly enhance the efficiency and accessibility of scRNA-seq data analysis.
Careful consideration of method-specific performance is crucial for reliable cell-type identification.
The developed package facilitates practical application and further research in automated scRNA-seq analysis.
