SeqLengthPlot v2.0: an all-in-one, easy-to-use tool for visualizing and retrieving sequence lengths from FASTA files

Area of Science:

• Bioinformatics
• Computational Biology
• Genomics and Proteomics

Background:

• Accurate sequence length profiling is crucial in bioinformatics, especially for genomics and proteomics.
• Existing tools like SeqKit and Trinity toolkit offer basic statistics but lack comprehensive analytics and plotting.
• Current tools often require multiple steps or separate programs for sequence length analysis.

Purpose of the Study:

• To introduce SeqLengthPlot v2.0, an integrated Python-based tool for sequence length profiling.
• To provide an easy-to-use, all-in-one solution for analyzing FASTA files.
• To enhance sequence analysis workflows by combining splitting, statistics, and plotting.

Main Methods:

• SeqLengthPlot v2.0 utilizes a command-line interface for user interaction.
• The tool processes nucleotide and protein FASTA files.
• It splits sequences based on a user-defined length cutoff and generates statistical summaries and length distribution plots.

Main Results:

• SeqLengthPlot v2.0 offers a unified approach to sequence length analysis.
• The tool generates comprehensive statistical summaries, including sequence counts and length distributions.
• It produces graphical representations (plots) of sequence length distributions.

Conclusions:

• SeqLengthPlot v2.0 simplifies and enhances sequence length profiling in bioinformatics.
• The tool's integrated approach saves time and effort compared to using multiple separate programs.
• SeqLengthPlot v2.0 is a valuable resource for researchers in genomics and proteomics.
