Bio-Tradis

Bio-Tradis analyzes Transposon Directed Insertion Sequencing (TraDIS) data from libraries of transposon mutants in isogenic populations to identify gene essentiality, gene function, and genetic interactions.

Key Features:

• Optimized protocol integration: Integrates an optimized library preparation and sequencing protocol tailored for TraDIS experiments to improve yield for downstream analysis.
• Extensible analysis pipeline: Implements an extensible Perl library that provides a modular pipeline for processing TraDIS sequencing data.
• Comprehensive data handling: Processes PCR-amplified transposon-containing DNA fragments and Illumina sequencing reads to analyze transposon insertion patterns for gene essentiality and function.

Scientific Applications:

• Gene essentiality studies: Determines essential genes under specific conditions by analyzing transposon insertion site distributions.
• Functional genomics: Elucidates gene functions and affected pathways by linking transposon insertion patterns to phenotypic effects.
• Genetic interaction mapping: Facilitates mapping of epistatic relationships and complex genetic networks from insertional mutant libraries.

Methodology:

The analysis pipeline is implemented as an extensible Perl library that processes Illumina TraDIS sequencing data to detect transposon insertion patterns and infer gene essentiality and function.
