peakScout-a biologist-friendly tool for bidirectional peak-gene mapping.

MOTIVATION: Translating genomic peak data into biologically meaningful knowledge typically requires bioinformatics expertise, creating a barrier for non-technical users. We developed peakScout to bridge the gap between peaks, genes, and gene annotations, enabling users to quickly focus on biological context rather than bioinformatics skills, in a reproducible and robust fashion.

RESULTS

peakScout is a command line and web-based program that performs bidirectional mapping between genomic peaks and genes. The peak-to-gene mode identifies which genes are potentially regulated by specific genomic regions, while the gene-to-peak mode reveals which regulatory elements might influence particular genes of interest. An algorithm for nearest-feature detection handles the complex spatial relationships between genomic elements, considering factors like distance constraints and feature overlaps.
