Species-Tree Node Confidence Audit
A tool that checks the reliability of each branch in an evolutionary tree to see which are trustworthy.
A tool that computes gene- and site-concordance factors for every node of a phylogenomic species tree and delivers a per-node confidence report, so labs, journals, and conservation bodies know which branches are trustworthy.
Concept
A "tree confidence audit" capability for phylogenomics labs. The user supplies gene alignments and their inferred species tree; the tool computes gene and site concordance factors for every node and returns a per-node report: which relationships are supported by a clear majority of genes, which are contested, and which alternative resolutions dominate. Output is a figure-ready conflict map plus a machine-readable reliability score per node that can be attached to a manuscript, a database record, or a conservation assessment. The wedge is routine, automatic discordance grading: because IQ-TREE 3 computes concordance factors inside the same workflow that infers the tree, checking node reliability becomes a standard step rather than a separate expert analysis. Downstream users matter too — comparative analyses that treat interspecific data in a phylogenetic context (e.g., morphometric integration and modularity studies [3]) inherit whatever error is in the underlying tree, so node-level reliability grades have value beyond the tree-builders themselves.
Why now
Paper [0] adds gene and site concordance factors for quantifying discordance between genomic regions directly inside IQ-TREE 3's maximum-likelihood workflow, and the release is tested on large phylogenomic datasets. Previously, discordance analysis required separate tools and specialist effort; now a single run yields both the tree and its per-node conflict grades. Phylogenomic datasets of hundreds to thousands of genes are now standard in biodiversity programs — especially in plants, where hybridization and genome duplication make gene-tree conflict the norm — so demand for routine conflict reporting rises at exactly the moment it became cheap to produce.

AI assessment
A focused utility that transforms complex phylogenomic discordance data into standardized confidence reports for academic and conservation publishing.
- Evidence strength 5/5
- The idea directly leverages the specific new functionality of IQ-TREE 3 (gene and site concordance factors) described in the full text to solve a known problem in phylogenomics.
- Market pull 3/5
- While the named beneficiaries are prestigious, the primary 'buyers' are likely academic labs and journals where the willingness to pay for a reporting tool (versus using the open-source software directly) may be limited.
- Novelty & moat 4/5
- It moves beyond simple tree inference to a 'confidence audit' and reporting layer, filling a gap between raw software output and publication-ready evidence.
- Feasibility 5/5
- Since the heavy computational lifting is already handled by IQ-TREE 3, the MVP is essentially a wrapper for data visualization and report generation.
- Wedge clarity 4/5
- The wedge is a specific, routine 'audit report' for manuscripts and conservation assessments, providing a clear entry point into the lab workflow.
- Simplicity / focus 5/5
- The product is a single, sharp tool with one clear purpose: auditing node confidence.

Who benefits
- Royal Botanic Gardens, Keworganization
Kew's Tree of Life programme builds plant phylogenies from hundreds of genomic regions, and plants are where hybridization and genome duplication make gene-tree conflict most common — exactly what concordance factors quantify.
- Natural History Museum, Londonorganization
The museum's biodiversity genomics groups publish large species trees; a routine per-node discordance report strengthens publications and flags introgression before it is missed.
- Smithsonian National Museum of Natural Historyorganization
Smithsonian runs large-scale comparative phylogenomics; node-level confidence grades show researchers and curators which relationships are safe to build classifications on.
Conservation prioritization increasingly uses evolutionary distinctiveness, which depends on trusting specific tree nodes; concordance grades show which nodes are robust before listing decisions lean on them.
