TreeGraph 2

TreeGraph 2 edits, annotates, integrates, and visualizes phylogenetic trees to combine multiple phylogenetic analyses and present node- and branch-level annotations for comparative evolutionary interpretation.

Key Features:

• Integration of Multiple Data Sources: Combines information from multiple phylogenetic analyses or dataset subsets to identify and present incongruences between different data sources or analytical methods.
• Versatile Annotation System: Attaches an unlimited number of annotations to nodes and branches, imports annotations from spreadsheets or other trees, and computes annotation values using user-defined mathematical expressions.
• Flexible Editing Operations: Supports rerooting, ladderizing, moving, collapsing nodes, manual de novo tree construction, and copying entire clades from other files while preserving associated data and legends.
• Customizable Visualization Options: Sets visual attributes such as line widths and colors based on node- or branch-level variables and applies formatting individually or across the entire tree.
• Data Management and Export: Filters, copies, or hides data associated with nodes and branches and exports trees in graphic formats including SVG, PDF, and PNG.

Scientific Applications:

• Comparative Phylogenetic Analysis: Integrates and compares results from different inference methods or datasets to detect and present conflicts or concordance among analyses.
• Annotation of Evolutionary Metrics: Maps branch- and node-level annotations such as support values or trait data onto tree topologies to aid interpretation of evolutionary relationships.
• Data Synthesis and Visualization: Synthesizes complex phylogenetic information from multiple sources into coherent tree visualizations for reporting and interpretation of evolutionary hypotheses.

Methodology:

Imports annotations from spreadsheets or other trees; computes annotation values via user-defined mathematical expressions; performs tree operations including rerooting, ladderizing, moving, collapsing, manual de novo construction, and copying clades while preserving associated data and legends; filters, copies, or hides node- and branch-associated data; exports graphics in SVG, PDF, and PNG formats.
