Telescoper

Telescoper assembles highly repetitive genomic regions, such as telomeres, from short-read sequencing data by integrating short-insert and long-insert libraries and extending read-overlap graphs to resolve complex repeat structures.

Key Features:

• Integration of short- and long-insert libraries: Telescoper utilizes both short-insert and long-insert sequencing libraries to enhance resolution of complex repeat patterns.
• Iterative extension through read-overlap graphs: The algorithm iteratively extends long paths across read-overlap graphs constructed from sequencing reads to build longer contiguous sequences through repeats.
• Statistical framework for evaluation: Assembled sequences are evaluated within a statistical framework to assess and validate assembly accuracy.

Scientific Applications:

• Telomere assembly: Telescoper targets telomeric regions with complex repeat structures, supporting studies of telomere evolution, function, and links to aging.
• Genome assembly of higher organisms: By resolving complex repeats, Telescoper contributes to de novo genome assembly of higher organisms where such repeats are prevalent.

Methodology:

Telescoper constructs read-overlap graphs from sequencing data from both short- and long-insert libraries, iteratively extends long paths through these graphs, and evaluates assembled sequences within a statistical framework.
