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 or click to the right of the Add Sequences tool () at the top left of the window and choose 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.
