PGT produces the highest resolution of geophylogenies, but is the easiest to use. Here are sample output:


  • Just a few clicks to install (see platform-specific installation below)
  • Click 'File|Open' to open a sample file, e.g., Banza.pgt (which is in plain text) that comes with installation.
  • Hold down the right mouse to drag the map
  • Use the middle mouse wheel to resize the geophylogeny on the map
  • Click the 'Map' menu to choose regular or satellite map
  • Click the 'Map|Raised|0.5' to see a raised geophylogeny.
For Windows 64-bit computers:

If your 64-bit Windows PC is new or updated, then you can launch PGT now. Otherwise, install and run PGT.

For Windows 32-bit computers:

If your 32-bit Windows PC is new or updated, then you can launch PGT now. Otherwise, install and run PGT.

For Macintosh and Linux computers with Mono installed (I tested PGT on Ubuntu Linux and Macintosh El Capitan):
  1. Download and unzip PGT.zip to a directory, say ~/PGT.
  2. Open a terminal windows and type the following commands:
    sudo apt-get install mono-vbnc (Otherwise you may encounter an error unless you have issued the command before)
    cd ~/PGT
    chmod 755 *
  3. Installation is now complete. For 64-bit MAC, type mono --arch=32 PGT.exe (Tip from Dr. Rutger Vos) to run PGT. For 32-bit Mac, just type mono PGT.exe to run.
  4. Here is a screenshot of PGT on Ubuntu with a satellite map, and another of PGT on Macintosh with a regular map.
