unitas: the universal tool for annotation of small RNAs

Area of Science:

• Small RNA biology
• Bioinformatics
• Genomics

Background:

• Next-generation sequencing (NGS) has revolutionized small RNA research, revealing diverse small non-coding RNA classes.
• However, annotating vast NGS datasets is challenging, requiring bioinformatics expertise and often limited by existing tools' sensitivity, species support, and subclass detection.

Purpose of the Study:

• To introduce unitas, a user-friendly software for comprehensive small RNA sequence annotation.
• To provide a robust and efficient solution for researchers, particularly those lacking bioinformatics support.

Main Methods:

• Developed unitas software for automated small RNA annotation.
• Integrated extensive species support using Ensembl databases (over 800 species).
• Implemented algorithms comparable to or exceeding existing annotation tools.

Main Results:

• unitas offers out-of-the-box functionality for complete small RNA dataset annotation.
• The software supports a wide range of species, facilitating broad research applications.
• unitas algorithms demonstrate performance on par with or superior to current annotation tools.

Conclusions:

• unitas consolidates annotation and analysis features, simplifying the process for non-expert users.
• The software addresses challenges like read normalization and provides high-quality annotation and analysis.
• unitas is a valuable, user-friendly tool for diverse small RNA biology research fields.
