OMWSA

OMWSA detects and maps DNA repeats by performing optimized moving window spectral analysis to visualize repeat location, period, length, and frequency on a two-dimensional spectrogram.

Key Features:

• Optimized moving window spectral analysis: Applies spectral analysis within adaptive moving windows to detect repetitive patterns in DNA sequences.
• Spectrogram generation: Generates a spectrogram that displays the distribution of repetitive sequences across the genome.
• Two-dimensional visualization: Visualizes repetitive DNA sequences on a two-dimensional plane mapping both their genomic location and frequency.
• Repeat period and length identification: Highlights repeat period and length and pinpoints precise repeat locations.
• Prior-knowledge-free detection: Identifies various types of DNA repeats without requiring prior knowledge of the sequences.
• Robustness to mutation and interleaving: Adapts to excessive mutation and interleaving within DNA sequence data to maintain detection performance.

Scientific Applications:

• Repetitive DNA characterization: Detects and characterizes repetitive DNA sequences for analysis of repeat architecture.
• Genetic diversity studies: Aids exploration of gene variation and genetic diversity arising from repeats.
• Gene regulation research: Supports investigation of regulatory functions of repetitive sequences and their influence on gene expression.
• Genomic architecture mapping: Provides insights into the location and distribution of repeats across genomes.

Methodology:

Performs optimized moving window spectral analysis to generate spectrograms that display the distribution of repetitive sequences across the genome, mapping repeat period, length, location, and frequency, with the moving window optimized to adapt to excessive mutation and interleaving.
