XS

XS simulates FASTQ reads for benchmarking and testing next-generation sequencing (NGS) data processing, compression, and infrastructure.

Key Features:

• Flexibility and Portability: Operates without requiring a reference sequence, enabling simulation independent of genomic references.
• Tunable Sequence Complexity: Provides adjustable sequence complexity to model different experimental conditions.
• Multiple Running Modes: Offers multiple running modes to optimize performance according to available time and memory resources.
• Component-Specific Simulation: Simulates FASTQ components—headers, DNA sequences, and quality scores—independently.

Scientific Applications:

• Computing infrastructure testing: Enables benchmarking of cloud computing platforms and other compute infrastructures.
• Large-scale project benchmarking: Supports evaluation of computational resources and algorithms for large-scale sequencing projects.
• FASTQ compression evaluation: Facilitates testing of FASTQ compression algorithms by generating reads with realistic sequencing characteristics.

Methodology:

Simulates FASTQ files with characteristics modeled after Ion Torrent, Roche-454, Illumina, and ABI-SOLiD sequencing platforms; performs component-specific simulation of FASTQ headers, DNA sequences, and quality scores; provides multiple running modes to trade off time and memory and operates without a reference sequence.
