gtrellis

gtrellis visualizes genomic data using Trellis graphics to display complex multivariate relationships across genomic categories.

Key Features:

• Trellis Graphics Layout: Employs a grid-based Trellis layout that partitions data by one or more categorical variables for parallel comparisons.
• Flexible Genomic Category Arrangement: Provides flexible arrangements of genomic categories on plots to organize genome-wide data layouts.
• Multiple-Track Visualization: Supports multiple tracks per panel to display several genomic properties in parallel.
• Extensible Framework with User-Defined Graphics: Allows incorporation of user-defined graphics into panels to extend visualization types.

Scientific Applications:

• Genome-wide high-dimensional relationship exploration: Enables exploration of high-dimensional relationships across the genome by arranging and comparing multiple features.
• Comparative genomics studies: Facilitates comparative genomics by enabling parallel visualization of different genomic features across categories.
• Pattern discovery in complex datasets: Aids identification of previously unrecognized patterns in genomic structures and functions through structured multivariate visualization.

Methodology:

Implements Trellis graphics with a grid-based layout that partitions data by categorical variables to enable parallel, multi-track comparisons across genomic categories and supports insertion of user-defined graphical panels.
