You can't just use the load() command. Try rh = MRIread(filename) The pixel data will be in rh.vol

Hi Bruce,
I just used the load command. See below.
load('rh.wang15_mplbl.mgz')
Error using load

Hi Mason
What do you mean you “just get a series of letters/symbols”? Can you send us the commands you ran and the screen output?
Cheers
Bruce

Hi Bruce and Doug,
I tried to load the overlay into Matlab, but that doesn’t work, I just get a series of letters/symbols. The surface overlay is in .mgz format. Using mri_cor2label works great for getting each roi into a label format, but I would also like them each in a .nii.gz format. Do you have any suggestions for this?
Cheers,
Mason

Hi Mason
You should be able to load the overlay and the ROIs into matlab, then pick out the vertices in each ROI from the overlay and save them separately. Just be careful about the one-based indexing in matlab. That is, if your ROI is in a label file and you read the vertex indices from it, you need to add 1 to the index that point into the overlay.
Cheers
Bruce

Hi Doug,
Yes, I mean a surface overlay, it is the mgz format. It essentially has 25 visual areas, shown in the attached. I wanted to split them up, so that each ROI is its own label. I saw I could use mri_cor2label, but is there a better way?
Cheers, Mason

When you say "surface" do you mean a surface overlay or a surface with xyz and neighbor relations? Assuming you mean an overlay (eg, something in an mgh or mgz file), you can try fscalc. Or do you have 25 frames in a single file and you want to split them into separate files? You might be able to convert the mgh/mgz file to nii and use FSL tools and then convert them back (sometimes works, sometimes not)

* External Email - Use Caution * Hi Experts, Apologies if this is a rather simple question. Is there a FreeSurfer equivalent of fslmaths? I have an atlas overlay that has 25 visual areas in a single .mgz file. I want to separate each atlas region into a different file, so that I end up with 25 surface atlas regions. Is there a command that could achieve this? My next question is whether or not there is a Freesurface command that can be used to complete surface based correlations. For example, if I want to check for the overlap between two ROIs. I have been using fslcc to do this in the volume, but perhaps freesurfer has something similar to do this on the surface?
