Convert Newick trees to Graphviz DOT format for visualization.

Input:

  • A Newick tree file.

Output:

  • Graphviz DOT format.

Notes:

  • Render with Graphviz tools such as dot, neato, or twopi (e.g., dot -Tpng tree.dot -o tree.png).
  • Node labels come from Newick node names; edge labels come from positive branch lengths. Styling information from necom nwk comment annotations is not rendered.

Examples:

  1. Convert to DOT necom nwk to-dot tree.nwk

  2. Save to file necom nwk to-dot tree.nwk -o tree.dot

  3. Create an image (requires Graphviz) necom nwk to-dot tree.nwk | dot -Tpng -o tree.png
