Revision History

June 21, 2007              Initial release for CATNAP Release 3.14b. (BL)

Step 1. Start the CATNAP Virtual Machine with VMWare Viewer. Log in as user “catnap” with the password “catnap”



Step 2. Start a terminal by clicking on the screen icon along the top of the window.


Step 3. Start Matlab by typing “matlab &”



Step 4.  Start catnap by typing CATNAP in Matlab.


Step 5.  Click “Add DWI File…” and select the sample “.par” files in the “Sample Data” folder



Step 6.  Click “select output path” and select the “processed “ folder within the SampleData folder.


Step 7. Change the scanner type to “3.0” and select the “Philips No Overplus Low” table.



Step 8: Click “Select .m File…” and select an m file to create for scripting.


Step 9. Click “Generate Processing Script”



Step 10. Go to the Matlab window. Change the directory to the same directory as your script file. Run the m file by typing the name of the m file (without “.m”) and press enter.


Step 12. After processing is complete, you may view the images in MIPAV (type “mipav &” in a terminal) or in Matlab.

Step 13: In Mipav, the dti contrasts may be opened as RAW files (256x256x65 at 0.828125x0.828125x2.2 mm).

The following are little endian floating point: FA, ADC, DXX, DXY, DXZ, DYY, DYZ, DZZ, MB0, MDW, eval1, eval2, eval3.

The following are little endian floating point vector: VEC (not easily ready in MIPAV)

The following is ARGB file: CMAP

Be sure to set the image orientation for proper 3D view:

Example of triplanar view in MIPAV:

Usage Tips

·         Fiber tracking may be done with the FA and VEC files on a Windows Platform. The FSL fiber tracking software is included, but not supported by the CATNAP developers.  

·         The virtual machine defaults with 256 MB of RAM. You may increase the settings to improve performance.

·         The root password is “password”.

·         The SampleData are available in already processed form in CATNAP_complete.tar.gz in the SampleData folder.

·         If you expose your virtual machine to the network, be sure to change both the user and root passwords.

·         To process data, we recommend keeping the data on the host computer and using the “shared folders” feature of VMWare to access the data. (The virtual machine’s hard drive is limited to 16 GB total.)
