Decision Forest is a novel pattern-recognition method which can be used to analyze:
- DNA microarray data
- Surface-Enhanced Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (SELDI-TOF-MS) data
- Structure-Activity Relation (SAR) data
Step 1: Verify that Java Running Environment (JRE) or Java Development Kit (JDK) 1.4.0 or later is installed on your PC. JRE and JDK may be downloaded from Sun Developer Network (SDN).
Step 2: Verify that java.exe is on your Path environment variable by following the steps below. If you experience difficulties, your system administrator may be able to help you.
- Click "Start" in the lower left-hand corner of your screen and then "Run" in the expanded list.
- Type "java" in the new window next to the command prompt and click "OK."
- You are ready to use Decision Forest if you see the following text after clicking "OK."
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args]
(to execute a jar file)
Please seek help from your system administrator if you do not see the text listed above.
Step 1: Save the forest.zip file to your local machine. In most browsers you can right-click and choose "Save As" to save the file to your hard drive.
Step 2: Unzip forest.zip to any directory.
Step 3: Double-click on the file named "run.bat" in the directory where the unzipped files were saved. This will launch Decision Forest.
The Quick Start Manual for Decision Forest is available for downloading.
