TE Density

TE Density quantifies the presence and distribution of transposable elements (TEs) relative to genes across a genome, producing per-gene metrics of TE occupancy and positional patterns for genomic analysis.


Key Features:

  • Comprehensive TE Analysis: Calculates the proportion of base pairs occupied by TEs within user-defined windows across the genome and reports these values per gene while recording TE descriptors such as order and superfamily.
  • Flexible Positional Analysis: Evaluates TE density in upstream, intragenic, and downstream regions using sliding windows to resolve positional distribution relative to genes.
  • User-Defined Parameters: Supports specification of window size for density calculations to analyze different genomic contexts and scales.

Scientific Applications:

  • TE-Gene Relationship Studies: Quantifies TE presence relative to genes to investigate potential influences on gene expression and genomic stability.
  • Genome Architecture Exploration: Maps TE distribution patterns to provide insights into structural organization of genomes.
  • Comparative Genomics: Enables comparison of TE distributions across species or strains to inform evolutionary analyses.
  • Diversity Analysis in TEs: Assesses the distribution of TE orders and superfamilies to explore TE diversity and potential functional implications.

Methodology:

Computes per-gene TE occupancy by leveraging gene and TE annotations and applying sliding-window calculations across upstream, intragenic, and downstream regions while recording TE descriptors such as order and superfamily.
