Installation procedures before you use COMKAT

System requirements

OS: Mac OS, Linux and Windows.
Matlab: As the mex files are compiled under different versions of Matlab, COMKAT on different platforms requires different Matlab release.

  • Windows: Matlab 7 and above
  • PowerPC-based Mac OS: Matlab R14 sp1 and above
  • Intel-based Mac OS: Matlab 2007a and above
  • Linux: Matlab R14 and above


1. Download

2. Unzip it to your computer.

3. Set up search path for COMKAT. You may do either of the following: (1) Open Matlab, run 'SetComkatPath.m' under the COMKAT root folder.
Or (2) You may set up the paths manually. First, open Matlab and go to File -> Set Path. Click 'Add folder' and select the following folders. (COMKATROOT is the root folder that you unzip COMKAT files under.)






After that, click 'Add subfolders' and select COMKATROOT/ImageReadingFunctions.

4. In Matlab, execute command 'validate'. Validation suite should pop up and allow you to examine if results are correctly generated on your computer.

NOTE Mac users: To display tables in the COMKAT GUI properly, you have to set up your Matlab startup option to show Java elements by following these steps:

  1. Find file named "Matlab" under Matlab_root/bin/mac (Matlab_root is your Matlab directory)
  2. Press "ctrl" and click on the file "Matlab" (at the same time)
  3. Select "Show Package Contents"
  4. Another finder window should popup showing "Contents", enter this folder
  5. Find a file named ""
  6. Open this file by TextEdit or any other editor
  7. Modify the following line: $SHELL -c 'bin/mac/setsid bin/matlab -desktop -display :0.0 &' to $SHELL -c 'bin/mac/setsid bin/matlab -useJavaGUI -desktop -display :0.0 &'
  8. Save ""


You can now test if comkat is properly installed by running the validation suite. NOTE: This step is NOT necessary if you have done the previous steps successfully.
