PCNVBrowser

This dataset contains comprehensive copy number variation (CNV) results generated from 3,202 whole-genome sequences across 26 populations in the 1000 Genomes Project. CNVs were identified using four widely used read-based detection algorithms (cn.MOPS, readDepth, CNVkit, and Control-FREEC), and the results have been systematically integrated to support population-scale and cross-tool analyses.In total, the resource includes 41,964 CNV files, organized at multiple levels of integration:Individual-level integration: CNV calls from four algorithms combined per individual sample.Tool-specific population-level integration: CNVs aggregated across individuals within each population for each detection tool.Population-level integration across tools: CNVs aggregated across all tools within each population.This structured dataset enables researchers to:Explore ancestry-specific CNV patterns across diverse populations.Compare algorithm-specific CNV detection outcomes.Benchmark detection tools on a unified dataset.Link CNVs to functional annotations and clinical resources through PCNVBrowser.The dataset serves as the underlying resource for PCNVBrowser (http://biweb.konkuk.ac.kr/PCNVBrowser/), an interactive web platform for exploring, comparing, and visualizing population-scale CNVs.
