Phylogenetic trees generated in MegAlign Pro can be opened in a compatible tree viewer using the File>Send Tree To… menu command. In order to use this functionality, you must first specify your desired tree-viewing application in MegAlign Pro by selecting Edit>Preferences. Compatible tree viewers include the following:

• FigTree*
• TreeView
• Archaeopteryx

Note: The File>Send Tree To… menu command is compatible with Archaeopteryx on Windows only. Newick or Nexus files exported from MegAlign Pro using File>Export Data>Tree can be opened in Archaeopteryx on both Windows and Macintosh.

*When installing FigTree on a Macintosh computer, you may receive a message that the application is damaged. You may need to change your Security & Privacy settings to allow applications downloaded from “Anywhere” in order to successfully install FigTree on Mac.

Note that phylogenetic trees generated in MegAlign Pro can also be exported in the Newick (*.newick) or Nexus formats (*.nex, *.nxs) using the File>Export Data>Tree menu command, and subsequently opened by many free and commercial evolutionary biology software programs.
