createcontrolsubset

createcontrolsubset filters duplicate reads from ChIP-seq aligned SAMPLE datasets and generates a duplicate-free CONTROL subset matched to the SAMPLE read count to support accurate peak calling.

Key Features:

• Duplicate Filtering: Removes duplicate reads from the SAMPLE aligned ChIP-seq dataset to reduce biases in peak calling.
• Control Dataset Creation: Produces a CONTROL dataset without duplicates that mirrors the SAMPLE read count for comparative analyses.
• File Format Compatibility: Accepts eland, sam, and bam file formats for aligned reads.

Scientific Applications:

• ChIP-seq peak calling improvement: Preprocessing by duplicate removal and matched control generation to help distinguish true binding sites from background signal in ChIP-seq experiments.

Methodology:

Operates within the Galaxy framework (including Galaxy@Pasteur) and is executed via the Galaxy API or the Bioblend library, utilizing the hosting instance's cluster resources.
