JVM: Java Visual Mapping tool for next generation sequencing read.

Area of Science:

• Bioinformatics
• Computational Biology
• Genomics

Background:

• Next-generation sequencing (NGS) technologies generate vast amounts of short DNA reads.
• Accurate and efficient mapping of these reads to a reference genome is crucial for genomic analysis.
• Existing alignment tools may face challenges with large datasets and specific sequencing technologies.

Purpose of the Study:

• To develop a novel Java-based program, Java Visual Mapping (JVM), for high-throughput sequence read mapping.
• To provide an efficient solution for aligning millions of short reads generated by Illumina sequencing technology.
• To support DNA sequencing (DNA-Seq) and RNA sequencing (RNA-Seq) applications, particularly for single-end resequencing.

Main Methods:

• Implementation of the JVM program in Java.
• Utilizing a seed-and-extend strategy for sequence alignment.
• Employing octal encoding operations to optimize alignment performance.
• Designing JVM as a desktop application with support for read data ranging from 1 MB to 10 GB.

Main Results:

• Successful development of the Java Visual Mapping (JVM) program.
• Demonstrated capability to handle millions of short reads from Illumina sequencing.
• Efficient sequence alignment using seed index and octal encoding techniques.
• JVM supports large read capacities, from 1 MB to 10 GB.

Conclusions:

• Java Visual Mapping (JVM) provides an effective solution for mapping next-generation sequencing reads.
• The program is well-suited for DNA-Seq and RNA-Seq resequencing projects involving large datasets.
• JVM's design facilitates efficient alignment of short reads, contributing to genomic data analysis.
