Getting Started

Install JDK8 and make sure that the path variable is set correctly. Test this by typing java -version into your terminal. It should respond with something like

java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)

Install Python on your system and ensure that it's mapped to the path variable such that it can be invoked through your terminal. Ideally the path variable will be named python, but if it's something else you may need to modify the source code to make it work - check Common Errors 2.

Running the project

Drag the entire folder into VSCode and click run on the top right corner. The first run will take some time to compile the project, but subsequent runs will be faster to initialize.

If you encounter an error, please read the error message and determine its source.

Common Errors

It's likely caused by the source stacks not having the Z and T channels switched. When the images are exported from the C10/Gen5, the images are stacked into Z layers instead of T (timepoints). These need to be switched manually through another ImageJ script prior to running this automated kalman tracker.

Python script isn't working - this is likely due to an issue with the way the python command is invoked on your system. Check this by typing python --version in your terminal. If this doesn't work, test it with other invokations like python3, py, or py3. Then replace the string in KalmanTrackerRunner.java from python to whichever invokation gave you a response in the line ProcessBuilder pb = new ProcessBuilder("python", "src\\Track-Spot_Merger_Auto.py", "--csvlist", csvArgumentString);.
