ChromoZoom

ChromoZoom provides genome browsing by pre-rendering and caching genomic tracks as tiled images to enable efficient visualization and reduce server load for analyses of human and yeast genomic datasets.

Key Features:

• Server-side pre-rendering and caching: Pre-renders and caches general-use genomic tracks into tiled images on the server to reduce per-request data processing.
• Tiled image delivery: Serves pre-rendered tiled images for visualization to minimize repeated server-side rendering of common tracks.
• Client-side rendering of custom tracks: Supports client-side rendering of custom tracks in various formats, localizing user-specific processing and avoiding transmission of private data.
• Support for multiple dataset types and assemblies: Handles curated, experimental, and personal genomic datasets and supports recent genome assemblies for human and yeast genomes.
• Rapid multi-track exploration: Enables rapid simultaneous exploration across diverse genomic data tracks.

Scientific Applications:

• Dataset visualization: Visualization and exploration of curated, experimental, and personal genomic datasets.
• Assembly inspection: Inspection and comparison of recent genome assemblies for human and yeast genomes.
• Privacy-preserving visualization: Visualization of private datasets via client-side rendering without transmitting underlying data.
• Resource-efficient deployment: Reduces server computation for common tracks in large-scale genomic data deployments.

Methodology:

Server-side pre-rendering and caching of general-use tracks into tiled images, serving those tiles to clients, and client-side rendering of custom tracks in various formats to localize user-specific processing and avoid transmitting private data.
