Generation of a binary mask of various brain regions

Hello Matlab-Experts,

I would like to install a Nifti.zip which allows me to open AAL files within MATLAB. Furthermore I would like to apply a binary mask for some brain regions and calculate a mean of each region(citalo and placebo).

Does someone know how to do it?

Thanks in advance, Chris

Hi Chris,

How have you managed to solve this?

Thank you.

@Ioannis Gkouzionis, what exactly is the problem:

1. Unzipping/extracting code and saving it
2. Opening AAL files as images
3. Setting a path to the new code (if necessary)
4. Segmenting the image into citalo and placebo regions. (Getting binary masks)
5. Doing the image analysis with the mask to get the area of each region.

Obviously #1 should be easy for you or any computer user.

I'm not sure what to tell you about unzipping the code and running it. Presumably you can figure that out yourself or with the help of someone next to you.

See my Image Segmentation Tutorial: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 and it will help you get regions and calculate means and centroids. Just replace imread() with your AAL file reader function.

Thanks for the answer. Am I right if I have to add to add the unzipped code at the directory set path? The content of the unzipped file can be seen here: http://en.pudn.com/downloads302/sourcecode/math/detail1347716_en.html

Thanks in advance, Chris

If you want to run that code then it must be on the search path. You can use the addpath(genpath()) command.
