T-lex2

T-lex2 genotypes individual transposable element (TE) insertions and estimates their population frequencies from individual-strain and pooled next-generation sequencing (NGS) data to support studies of TE contributions to genome function and evolution.

Key Features:

• Automatic genotyping: Precisely identifies presence/absence of individual TE insertions from NGS data.
• Population frequency estimation: Estimates population frequencies of TE insertions using both individual-strain and pooled NGS data.
• Quality assessment: Evaluates genotyping-call quality, identifies mis-annotated TEs, and provides information for re-annotation.
• Flexibility and customization: Configurable to analyze different genomes and TE insertion types.
• Validation across genomes: Performance tested on fly and human genomes.

Scientific Applications:

• Genome function and evolution: Supports analysis of the contribution of TEs to genome function and evolutionary processes.
• TE dynamics and evolutionary roles: Enables studies of TE insertion dynamics and their roles in evolution.
• Genomic architecture: Facilitates investigation of how TE insertions influence genomic architecture through genotyping and frequency estimation.

Methodology:

T-lex2 analyzes next-generation sequencing (NGS) data from individual strains and pooled samples using an algorithmic framework that performs genotyping and incorporates quality-control measures to refine TE annotations.
