An example of a decision-tree and its corresponding set of rules able to predict surgical phases are available here: decision-tree-ipcai2015.txt.
The software is developed in Java, it uses the Weka classification library.
The package is licensed under a GPLv3 (license in the Jar files) : donwload the soure code.
The package contains a sample file (sample.arff) that can be used to test the program.
To run the program just execute:
java -jar ipcai2015.jar sample.arff in a console.
