htseq-clip

htseq-clip extracts and summarizes nucleotide-resolution crosslink site counts from iCLIP and eCLIP sequencing data to support identification and comparison of RNA-binding protein binding sites across the transcriptome.

Key Features:

• Preprocessing: Performs essential preprocessing of raw iCLIP and eCLIP sequencing data to prepare reads for downstream analysis.
• Crosslink Site Count Extraction: Extracts nucleotide-resolution crosslink site counts from processed iCLIP/eCLIP reads.
• Summarization and Metrics Generation: Summarizes crosslink counts into matrices and generates additional metrics for filtering and downstream analyses.
• Differential Binding Site Identification Support: Produces outputs applicable to identification and comparison of differential RNA-binding protein binding sites across samples or conditions.

Scientific Applications:

• Transcriptome-wide RBP mapping: Enables analysis of transcriptome-wide RNA-binding protein binding patterns at nucleotide resolution using iCLIP and eCLIP data.
• Comparative differential binding analysis: Supports comparative studies of changes in RNA–protein interactions across biological states or experimental conditions.

Methodology:

Implemented in Python, htseq-clip performs preprocessing of iCLIP/eCLIP reads, extracts nucleotide-resolution crosslink site counts, summarizes counts into matrices, and generates metrics for filtering and downstream differential binding analyses.
