RBrowser User Interface¶
1. Overview¶
The RNA Browser UI is divided into five key regions:
- Toolbar (top) – Global menus and controls
- Sidebar Views (left) – Track management and annotations
- Main Browser View (center) – Continuous, RNA-centric signal display
- Plugin System (right) – Extensible panels for structures and interactions
- Status Bar (bottom) – Coordinates, load status, and notifications
2. Toolbar¶
- Menus: File, Data, Tracks, Selection, Edit, View, Help
3. Sidebar Views¶
- Search: Provides a global search box to locate genes, transcripts, coordinates, or keywords across loaded datasets.
- Track: Manages all data tracks that render within the main browser.
- Region: Enables precise control over the genomic range displayed.
- Bookmark: Save and organize regions of interest for later review.
- History: Keeps a chronological log of your actions within the session.
- DataHub: Interface to external data sources and repositories.
- Plugin: List and configure optional extensions that enhance the core browser.
4. Main Browser View¶
- Annotation Channel
RNA annotations channel: single-molecule mods, m6A, Ψ, exon, junction, CCRE, RBP, eQTL, sQTL and Other singals - Expand Channel
Expand each channel to view per-sample datasets (e.g. HeLa, HEK293T, HSC d0/d3/d6/d9) - Controls
Collapse/expand, remove, adjust opacity or color mapping - RNA-Centric Signals
Converts discrete DNA-coordinate features into smooth, continuous tracks focused on transcript coordinates - Isoform Visualization
Exons and junctions rendered as arrowed segments indicating structure & direction - Multi-track Overlay
Vertically stacked tracks for side-by-side comparison of binding, structure, modifications, splicing - Interactive Navigation
Click-and-drag panning, scroll-wheel zooming, real-time redraws
5. Plugin System¶
- RNA 2D Structure
- Secondary-structure diagram; zoom, pan & export
- RNA 3D Structure
- Interactive 3D folding model with rotation controls
- Chromatin-Associated RNA
- 3D view of RNA–chromatin contacts
- RNA Interaction Network
- Graph of RNA–RNA and RNA–protein interactions; nodes color-coded by molecule type (protein, miRNA, lncRNA, mRNA, ncRNA)
6. Status Bar¶
- Coordinates & Scale
- Displays chromosome, start–end positions, and zoom scale (bp/pixel)
- Load & Cache Status
- Icons/text for data-loading progress, cache hits, thread utilization
RNA Browser transforms discrete genomic coordinates into a unified, RNA-focused visualization framework. By integrating multi-modal annotations and extensible plugins—spanning secondary and tertiary RNA structures through interaction networks—it provides researchers with an intuitive, high-resolution platform for exploring RNA–DNA crosstalk and transcriptome regulation.
