JPathfinder is the Java version of the software. It runs on any computer with an up-to-date version of Java (free). Some sample data files and a terms file are placed in a "jpf" directory for experimentation. This software is now very stable, but please report any problems or bugs. You also should download fresh copies before starting new projects to take advantage of any fixes that have been made.

If you run into problems running the jar files, it could be due to a problem with file type associations on your computer. The easiest and most effective way to solve this problem is to run a small program called jarfix developed by Johann Löfflmann. Search for jarfix, and you will find sites for downloading jarfix.exe. Run this program once, and it will setup the proper file associations to allow you to run executable jar files by simply double clicking them.

Matlab version of Pathfinder (9.0)

A MATLAB Pathfinder APP is available. It creates a folder, "pfdir" in your user folder. The folder, pfdir, is used by the APP and it contains some sample proximity data and terms files to get you started.

Download Pathfinder 9 for PC (Windows) ............. Updated 21 Sep 2023

The Mac version cannot be updated so an older version is all that is available. Download Pathfinder 9 for Mac ... 22 Feb 2017

You can also download an App for MATLAB which also requires the Statisics and Machine Learning Toolbox.

You may run into some permission issues when installing the software. On the PC, Windows may try to prevent installation, but clicking "more info" will give you the option of opening it anyway. On the Mac, you first have to unzip the app by double clicking the zip. This usually goes ok, but then when you try to open the Installer, you will get the "Unknown Developer" message. Try right clicking (or Control click) and then Open. When that doesn't work, try it again and you should get the option to open it anyway.

Windows "protection" may cause some problems installing the app. Look at the following for information:

Documentation is accessible from the APP under "Help"
