CRUISE quick-start guide

1.	Open MIPAV v4.1.2 and check the Plugins menu to ensure that the CRUISE plugin has been installed (MedIC Downloads).
2.	Open a stripped image, then open the CRUISE plugin. The interface will automatically open to the TOADS 2007 tab.	CRUISE plugin
3.	In the drop-down menu in the Image to segment section, choose the image you want to work with. The list provided here will include any images you currently have open. If you want to open another image, you may either open it through the MIPAV file menu or browse to the image within the CRUISE interface using the Browse button under the Image to segment area.	Image to segment
4.	Under Image modality, make sure the proper type of image is selected.	Image modality
5.	Under Atlas file, input the path for the template you wish to use. You may use the text file from the TOADS atlas to begin with [1], or input another atlas text file of your choice.	Atlas file
6.	Modify any other parameters you wish to change (link to extended guide). You should be able to get a decent result without changing any other options.	All necessary options filled
7.	Click on the OK button at the base of the plugin interface to begin processing. A window will pop up in which you may indicate where you want to save the output files. Once you have chosen a location, press the Save button in this window, and the processing will begin.	Choose output directory TOADS progress bar
8.	You will immediately see a very large jump in memory use by MIPAV. If you have enough memory that is not allocated to MIPAV, you may use your computer with the process running in the background. If you find your processes are lagging, leave your computer alone until the iterations are complete.
9.	After processing has finished, there should be several output folders, all within a folder named cruise which will be in the same directory as your input file. These folders should include ace, crop, gvf, tgdm, Toads07, and topo_correct. Please see the extended guide for more information on the output files in each of these folders (link to extended guide).	cruise output directory Folders within cruise
10.	To view a topological reconstruction of the extracted cortical surfaces, you may look at the files within the tgdm folder.	tgdm contents

CRUISE extended guide

As soon as I have finished more of the extended guide, there will be a short description and link to it here. Cortical surface viewing instructions Instructions for viewing in MIPAV As soon as this is possible, I will put instructions here. Instructions for viewing the surface images with ParaView 1. Install ParaView 3.2.1. 2. Open Paraview Paraview 3. Browse to the .vtk output images using the File menu. When you have selected the surface file you would like to view (inner, middle, or outer surface), click on the OK button at the bottom of the file selection window. Select .vtk file to view 4. The filename of the image you have chosen will appear in the upper left side of the interface. Surface file loaded 5. To visualize the surface, press the Apply button under the Properties tab in the lower left side of the interface. This will result in a three-dimensional display of the image you have chosen in the large grey box on the lower right side of the interface. 3d surface view Using the Volume Converter Plugin in MIPAV To view individual slices with nested surfaces, it is necessary to use the Volume Converter plugin in MIPAV. 1. Open MIPAV and your source image, and go to the Volume Converter plugin. Volume Converter 2. Under the Volume area of the interface, use the drop-down menu to choose your source image. If you want to open another image, you may do so using the Browse button. Select source image 3. Use the drop-down menu under File Type to select the type of output file you wish to generate.

Next, you will be required to input a target directory for saving the output file. When you have selected this directory, press the Save button. Select output directory 5. A box will appear when the plugin has finished converting your source image to a vtk file. Conversion is complete Viewing Nested Surfaces in Paraview 1. Open Paraview. Paraview 2. Use the File menu to browse to the output folder for the Volume Converter, which will be named volconvert. Volume Converter output folder 3. Select the .vtk file inside the volconvert folder and press the OK button. Select .vtk file 4. Your selected .vtk file will be visible in the upper left side of the Paraview interface. .vtk file loaded 5. On the lower left side of the interface, click on the Display tab.

Color Scale Color Scale adjustment 9. Use the File menu to browse to the outer surface vtk file. Press the OK button once you have selected the file. Once it is loaded in Paraview, press the Apply button. Load outer surface file 10. Use the File menu to browse to the inner surface vtk file. Press the OK button once you have selected the file. Once it is loaded in Paraview, press the Apply button. Load inner surface file 11. Once the surface files are loaded, click on the Group Datasets icon, which is the second button from the right on the toolbar immediately above the upper left side window containing the loaded filenames (this icon is marked with a red circle on the Group Datasets image). After you have clicked on this icon, press the Apply button. Surface files loaded Group Datasets 12. Next, locate the Cut icon. This is the fourth button from the left on the toolbar immediately above the upper left side window containing the loaded filenames (this icon is marked with a red circle on the Cut image). Press the Apply button after using the Cut tool. Cut 13. Go to the Properties tab and locate the Normal subsection of the Slice Type: Plane area. Modify these values according to the acquisition orientation of your source image. For example, if you have used an axial image, change to values in the Normal section to 0,0,1. Reset orientation Viewing Labeled Surfaces in Paraview 1. Label your CRUISE surface. There are many ways to do this. A brief overview can be found here. 2. Open Paraview. Paraview 3.
