Hi,

I am a newbie in using freesurfer so sorry if this is a very trivial question. I want to load my fMRI data into matlab. I want to make a matrix containing coordinates and values of all the voxels in the brain at all timepoints. I also only want the voxels that are in the gray matter and not the voxels that are in the white matter or outside the brain. Where can I get this data and how can I load it to matlab? I have already managed to import all the voxels using MRI- ldbvolume, but this includes white matter and skull. How can I get rid of the rest of the brain and just get the surface?

Bests, Maryam.
