gCrisprTools

gCrisprTools analyzes pooled high-throughput CRISPR/Cas9 and short hairpin RNA (shRNA) screening data to evaluate library and cassette behavior, identify differentially abundant cassettes, aggregate signals, and prioritize candidate targets.

Key Features:

• Library and Cassette Behavior Analysis: Implements methods to quantify and characterize the behavior of libraries and individual expression cassettes across experimental conditions.
• Identification of Differentially Abundant Cassettes: Identifies cassettes showing differential abundance across samples or conditions.
• Signal Aggregation and Candidate Target Identification: Aggregates signals from high-throughput screening data to support identification and prioritization of candidate targets.
• Comprehensive Reporting: Produces detailed analytical outputs and visualizations of screening results.

Scientific Applications:

• Functional Genomics Studies: Analyzes CRISPR/Cas9 and shRNA pooled screens for gene function discovery.
• Gene Knockdown Experiments: Supports analysis of shRNA-mediated gene knockdown experiments to assess effects on cassette abundance.
• Genome-wide Screens: Processes genome-wide CRISPR/Cas9 and shRNA screens to identify genetic elements influencing experimental phenotypes.
• Target and Pathway Identification: Facilitates identification of genetic targets and pathways involved in biological processes and diseases.

Methodology:

Built on Bioconductor principles and implemented in the R statistical programming language for rigorous statistical analysis and reproducibility.
