SeqKit: A Cross-Platform and Ultrafast Toolkit for FASTA/Q File Manipulation

Area of Science:

• Bioinformatics
• Computational Biology
• Genomics

Background:

• FASTA and FASTQ formats are fundamental for storing biological sequences.
• Existing tools for FASTA/Q manipulation are often limited in functionality, efficiency, or cross-platform compatibility.
• Complex installations and dependencies hinder the usability of current bioinformatics tools.

Purpose of the Study:

• To introduce SeqKit, a novel, ultrafast, and comprehensive toolkit for FASTA/Q file processing.
• To provide a user-friendly, cross-platform solution for common sequence data manipulations.
• To enhance the efficiency and accessibility of sequence data analysis for researchers.

Main Methods:

• Development of a cross-platform toolkit providing executable binary files for Windows, Linux, and Mac OSX.
• Implementation of diverse FASTA/Q file manipulations including conversion, searching, filtering, deduplication, splitting, shuffling, and sampling.
• Optimization for competitive performance in execution time and memory usage.

Main Results:

• SeqKit offers a unified solution for a wide range of FASTA/Q manipulations.
• The toolkit is easily deployable across major operating systems without external dependencies.
• SeqKit demonstrates superior or competitive performance compared to existing tools in terms of speed and memory efficiency.

Conclusions:

• SeqKit significantly improves the usability and efficiency of common FASTA/Q file manipulations for researchers.
• Its cross-platform nature and ease of use make it a valuable tool in bioinformatics and genomics.
• The open-source availability encourages community adoption and further development.
