TreeView

TreeView displays phylogenetic trees and provides visualization and annotation features to inspect tree topology, branch (edge) lengths, and internal node labels.

Key Features:

• Supported input formats: Reads tree files in NEXUS, PHYLIP, Hennig86, Clustal and related formats.
• Tree annotations: Displays edge (branch) lengths and internal node labels.
• Tree manipulations: Supports rerooting and altering the order of terminal taxa, and iterating through multiple trees contained in a single file.
• Export and interoperability: Saves trees and exports graphics in multiple formats, including PICT and Windows metafiles, to enable transfer between phylogenetic analysis programs.

Scientific Applications:

• Phylogenetic visualization: Visualize tree topology, branch lengths, and node labels to interpret evolutionary relationships.
• Topology inspection: Assess alternative rootings and taxon orderings to examine clade structure and presentation.
• Data exchange: Export trees and graphics for downstream analysis or integration with other phylogenetic programs such as PAUP and MacClade.

Methodology:

Parses tree files in NEXUS, PHYLIP, Hennig86 and Clustal formats; renders tree topology with edge lengths and internal node labels; provides rerooting, terminal-taxa reordering, sequential traversal of multiple trees in a file; exports trees and graphics in various formats including PICT and Windows metafiles.
