IGV Web Tool

IGV Web Tool renders aligned reads, variants, and annotation tracks in a browser. Users load BAM/CRAM, VCF, BED/BigWig data for a chosen genome build and region. It supports multi-track views, coordinate-based queries, and client-side caching for smooth exploration. Conceptually, data are streamed or opened from local files, decoded, and visualized as coverage bars, read layouts, and variant markers. The tool emphasizes rapid inspection, reproducibility, and easy sharing of views across researchers. Unique value comes from browser-native operation, support for remote data sources, and lightweight export options for figures or configurations. Core features include: (1) coordinate navigation, (2) multi-track rendering, (3) basic filtering by quality or allele, (4) local and remote data access, (5) per-track configuration and color-coding, (6) export of current view to JSON or image, and (7) region-based queries for quick checks across samples. Use cases include QC checks on sequencing runs, variant validation in a genomic interval, and preparing visuals for reports or publications. The tool is designed for researchers, clinicians, and data managers who need a fast, install-free visualization experience with data privacy preserved in the browser. Performance is optimized for moderate data sizes and streaming segments from remote servers when supported.
