MegAlign Pro can open Newick trees with .newick, .txt or .tree extensions.

To import a Newick-format tree file:

  1. Make any MegAlign Pro project tab active, or open a new, blank project. Trees cannot be opened from within the Welcome screen
  1. Choose File > Add Trees.
  1. Select one or more Newick tree files and choose Open. Each tree is added as a named tree in the Tree view tab and the Explorer panel, as described above. The tree name is the same as the file name.
  1. (optional) If desired, repeat Step 2 to add additional trees.
