Phylogenetic tree of 5 FMDV genomes

Phylogenetic tree of IAV HA gene sequences

Features

• Interactively view your tree in the browser with metadata highlighted beside your tree using PhyloCanvas.

• Automatically retrieve metadata from a GenBank file!

• Visualize your own metadata! Provide a tab-delimited table as input with --user-sample-metadata /path/to/your-table.tsv

• Highlight branches with low support in the browser.

• Collapse branches with low support (e.g. -C 95 for IQ-TREE trees with UFBoot -bb 1000 to collapse branches with less than 95% support).

Usage: shiptv [OPTIONS]

  Create HTML tree visualization with metadata.

  The metadata for reference genomes can be extracted from the specified
  Genbank file.

  Any leaf names that are present in the tree but not present in the Genbank
  file are assumed to be user samples and are flagged as such in the
  metadata table as "user_sample"="Yes".

Options:
  -r, --ref-genomes-genbank FILE  Reference genome sequences Genbank file
  -n, --newick FILE               Phylogenetic tree Newick file  [required]
  -N, --output-newick PATH        Output Newick file
  -o, --output-html PATH          Output HTML tree path  [required]
  -m, --output-metadata-table PATH
                                  Output metadata table path  [required]
  --leaflist PATH                 Optional leaf names to select from
                                  phylogenetic tree for pruned tree
                                  visualization. One leaf name per line.
  --genbank-metadata-fields PATH  Optional fields to extract from Genbank
                                  source metadata. One field per line.
  --user-sample-metadata PATH     Optional tab-delimited metadata for user
                                  samples to join with metadata derived from
                                  reference genome sequences Genbank file.
                                  Sample IDs must be in the first column.
  --metadata-fields-in-order PATH
                                  Optional list of fields in order to output
                                  in metadata table and HTML tree
                                  visualization. One field per line.
  --dont-fix-metadata             Do not automatically fix metadata (only on
                                  Genbank file metadata)
  -C, --collapse-support FLOAT    Collapse internal branches below specified
                                  bootstrap support value (default -1 for no
                                  collapsing)
  --help                          Show this message and exit.

With a reference sequence Genbank file ref.gb, a Newick format phylogenetic tree tree.nwk, output a tree.html standalone HTML interactive phylogenetic tree visualization and a metadata-table.tsv tab-delimited table of metadata from ref.gb.

shiptv -r ref.gb -n tree.nwk -o tree.html -m metadata-table.tsv
