Background:

  • Repetitive DNA sequences are a significant feature of genomes.
  • Efficient computational methods are needed for analyzing repetitive genomic structures.
  • Suffix trees offer a powerful data structure for sequence analysis.

Purpose of the Study:

  • To develop and present a novel computational system for the analysis of repetitive genomic structures.
  • To introduce a new clustering method for organizing repeat data.
  • To provide a software tool for identifying and classifying repeats in large-scale genomic datasets.

Main Methods:

  • Utilizes suffix trees for organizing and searching genomic sequences.
  • Employs a new clustering method for repeat data analysis.
