Management of High-Throughput DNA Sequencing Projects: Alpheus.

Area of Science:

• Genomics and Bioinformatics
• Systems Biology
• Computational Biology

Background:

• High-throughput DNA sequencing generates vast amounts of complex data.
• Managing and analyzing this data is crucial for biological research.
• Existing tools may not efficiently handle the scale and complexity of modern sequencing.

Purpose of the Study:

• To introduce Alpheus, a comprehensive software solution for analyzing massively parallel DNA sequencing data.
• To provide tools for variant detection, sequence abundance enumeration, and differential expression analysis.
• To facilitate data management and visualization for systems biology applications.

Main Methods:

• Alpheus is an analysis pipeline, database, and visualization software.
• It supports short-read, multi-gigabase throughput sequencing technologies (e.g., Illumina-Solexa, Roche-454, SOLiD).
• Features include sequence alignment, variant detection (SNPs, indels, etc.), and expression level analysis.

Main Results:

• Alpheus detects various genetic variants, including SNPs, indels, and splice isoforms.
• Variant detection is enhanced by filtering options to minimize false positives.
• The software enables comparisons between cases and controls and differential expression analysis.

Conclusions:

• Alpheus provides a robust platform for analyzing diverse high-throughput sequencing data.
• It supports critical tasks in genetic variant discovery and gene expression profiling.
• The software aids researchers in health, agriculture, and basic biological research.
