Installation

1. Download COMKAT_R3.zip.

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.)

COMKATROOT/

COMKATROOT/comkat_GUI

COMKATROOT/ComkatImageTool

COMKATROOT/utilities

COMKATROOT/validation

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 " launch_matlab.sh"
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 "launch_matlab.sh"
