pilercr

pilercr identifies and analyzes CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) elements in prokaryotic genomes for detection and cataloging of repeat arrays in genomic and evolutionary studies.

Key Features:

• Specialization for CRISPR Repeats: Tailored specifically for detection and analysis of CRISPR repeats, improving accuracy compared with generic repeat-finding tools.
• High Efficiency: Processes a 5 Mb genome in approximately 5 seconds, supporting rapid large-scale genomic analyses.
• Validation and Accuracy: Results have been validated by manual curation and comparison with published surveys of CRISPR repeats, demonstrating high sensitivity and specificity.
• Comprehensive Analysis Capability: Applied to a comprehensive analysis of 346 prokaryotic genomes, producing a catalogue of putative CRISPR repeats.

Scientific Applications:

• Genomic surveys: Rapid identification of CRISPR arrays across prokaryotic genomes for large-scale genomic surveys.
• Comparative genomics: Comparative genomics studies of CRISPR repeat sequences and array structures.
• Evolutionary studies: Investigation of the distribution and evolution of CRISPR elements and CRISPR-Cas systems.
• Microbial community analysis: Analysis of CRISPR element distribution and potential functions within microbial communities.

Methodology:

Computational identification and analysis of CRISPR repeat arrays in genomic sequences; benchmarking includes runtime measurement (~5 seconds for a 5 Mb genome) and validation by manual curation and comparison with published CRISPR surveys; applied to analysis of 346 prokaryotic genomes to produce a catalogue of putative CRISPR repeats.
