<p>I have plenty of experience in EEG analysis but I have never worked with fMRI. I want to parcellate the fMRI data using the Yeo 7 resting state networks parcellation. I found a NIFTI file about this specific atlas on Fieldtrip Toolbox but I do not know how to go from the 4-D matrix of the functional NIFTI to a 2-D matrix of network activity. While I can do some coding in Python, I would prefer a MATLAB solution. I have seen several toolboxes but I cannot find a straightforward answer/tutorial. Can anyone point me to the right direction?</p>

There's a lot of nuance to this type of work; you probably need to find someone experienced to walk you through it. Not something you can learn from a tutorial, which might tell you how to use particular software but won't get you through all the various decisions to make. It's not quite so straightforward.

Yeah good points, but the data I found are already preprocessed and in the MNI space. I ended up finding the solution at CONN Toolbox. I just had to load my files, load the Yeo 7 atlas (found in the "otherrois" folder of the toolbox) and then select extract BOLD time series (at the preferences tab). Overall, this is a pretty nice toolbox.

Ah, yes, a lot easier if the preprocessing is complete.
