To analyze and visualize phylogenetic trees, you can load Newick or NHX files to reroot, prune, and traverse tree topologies. This workflow generates clean PDF, SVG, or PNG publication figures with custom styles and annotations.

Detect orthologs and paralogs in a gene family tree by evaluating duplications and speciations across the topology. This phylogenomic analysis automatically extracts evolutionary events and splits gene families into annotated orthology reports.

Yes, you can query NCBI taxonomy to build species trees and evaluate hierarchical clustering. This requires ETE3 tree handling to access taxonomic databases and apply taxonomy annotation to your phylogenetic workflow.

The best way to reroot and prune phylogenetic trees is using scriptable CLI helpers for deterministic tree operations. This approach resolves polytomies, exports Newick or NHX formats, and produces publication-ready annotated visualizations.

Yes, ETE3 supports custom layouts and annotations for tree visualization. You can generate clean publication figures in PDF, SVG, or PNG formats with custom styles applied directly to your phylogenetic tree topologies.

Resolving polytomies matters before comparing tree topologies because it ensures deterministic branching order for accurate phylogenetic analysis. Multifurcating nodes can obscure speciation and duplication events during orthology detection and tree comparison.
