Selecting a Workflow
 
        - Choose a Workflow- Placement workflow (Fast): Automatically places uploaded genomes into a pruned GTDB-based reference tree using Mash distance. Suitable for quick, high-level placements.
- De novo workflow (Accurate): Allows custom tree construction using selected organisms and genes. Suitable for in-depth phylogenetic analysis.
 
Placement (Lite) Workflow
 
        - Upload genome file(s) in FASTA or GenBank each containing one organism.
- Optional: provide an email for job updates, a title, or save the job to your browser (via cookies).
De novo Workflow
Step 1 Submit Sequences
 
             
        - Upload up to 50 genome files. Same format requirements as above.
- Choose tree type:
                    - Concatenated: Concatenated Phylogeny, using concatenated matrix.
- Coalescent: Default MLST tree, based on gene tree consensus.
 
- Optional parameters:
                    - Enable automatic species/gene selection.
- Enable bootstrapping (Ultrafast Bootstrap).
- Enable ModelFinder for best-fit models.
 
- Optional job parameters (email, title, cookie storage).
Step 2 Species and Outgroup Selection
 
             
             
        - Edit default selection of 50 closest genomes. Exceeding selections are ignored.
- Filter, search, and explore metadata for selected and additional species.
- Optionally select your desired outgroup genome.

Mash-based ANI Estimation
 
        - ANI table shows closest matches by Mash distance. Search and sort functions available.
Tree
 
             
                 
                 
             
                 
                 
        Tree types and options vary by workflow. Tree nodes are color-coded (QS = blue, OG = red, TS = green).
- Toggle between scaled and unscaled branch display.
- Search and highlight organisms in the tree.
- Display options include:
                    - Highlighting BGC potential
- Strain info highlighting
- Highlighting a specific BGC group
 
- Additional data about reference genomes
- Downloads:
                    - Newick tree (no color)
- SVG tree image
- Alignment files (ZIP) (denovo only)
- Gene list (denovo only)
