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.

• Visualize your own metadata! Provide a tab-delimited table as input with --metadata your-metadata-table.tsv

• Select metadata fields to display beside phylogenetic tree with select box

• Automatically retrieve metadata from a GenBank file!

• 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).

• Toggle full window mode with shift+ctrl+f. Works well with F11 fullscreen mode.

Usage

Show help info:

$ shiptv --help

Install shiptv completions for current shell:

$ shiptv --install-completion

Most basic usage would be to create a tree from a Newick format tree file:

$ shiptv -n newick.treefile -o shiptv-tree.html

More advanced usage would be to provide a tab-delimited table of metadata with the first field containing sample names identical to those in the Newick tree file:

$ shiptv -n newick.treefile --metadata my-metadata.tsv -o shiptv-tree.html

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

Help output

$ shiptv --help
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".

  -n, --newick PATH               Phylogenetic tree Newick file  [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.

  -M, --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.

  --fix-metadata / --no-fix-metadata
                                  Try to automatically fix metadata from
                                  reference Genbank file.  [default: True]

  -C, --collapse-support FLOAT    Collapse internal branches below specified
                                  bootstrap support value (default -1 for no
                                  collapsing)  [default: -1.0]

  --highlight-user-samples / --no-highlight-user-samples
                                  Highlight user samples with metadata field
                                  in tree.  [default: False]

  --outgroup TEXT                 Tree outgroup taxa
  --midpoint-root / --no-midpoint-root
                                  Set midpoint root  [default: False]

  --install-completion            Install completion for the current shell.
  --show-completion               Show completion for the current shell, to
                                  copy it or customize the installation.

  --help                          Show this message and exit.
