isChIP

isChIP simulates Chromatin Immunoprecipitation followed by Next-Generation Sequencing (ChIP-seq) to model transcription factor and chromatin-associated protein binding and to optimize experimental and analytical parameters.

Key Features:

• Realistic Simulation: Simulates the ChIP-seq process to approximate experimental conditions and produce data resembling real sequencing experiments.
• Sequencing Platform Support: Implements simulations based on the Illumina protocol and supports simulation across Roche454, Ion Torrent, and SOLiD platforms.
• ChIP-Exo Simulation: Provides simulation of ChIP-Exo data in addition to standard ChIP-seq.
• A-priori Binding Templates: Utilizes a-priori known binding templates to generate simulated binding events.
• Validation and Benchmarking: Includes validation using publicly available datasets and comparative analyses against existing ChIP-seq simulators.
• Modeling of Diverse Binding Events: Models a broad range of binding events for transcription factors and chromatin-associated proteins.
• Data Analysis Benchmarking: Enables benchmarking and comparison of ChIP-seq analysis programs to inform analytical software selection.

Scientific Applications:

• Transcription factor and chromatin interaction studies: Modeling interactions between transcription factors, chromatin modifiers, and DNA.
• Experimental protocol optimization: Optimizing ChIP-seq experimental parameters prior to wet-lab implementation.
• Analysis software evaluation: Benchmarking and selection of ChIP-seq data analysis programs.

Methodology:

Simulates the ChIP-seq process approximating experimental conditions; implements Illumina-based simulations and supports Roche454, Ion Torrent, and SOLiD; simulates ChIP-Exo; uses a-priori known binding templates; validated using publicly available Oct4 and Sox2 datasets and comparative analyses with existing simulators.
