Hi Guys,
I want to calculate the intensity values of each voxel in a 4dim resting-fmri Nifti image. The dimensions of my 4dim image are: 45*54*45*90.
Is there any matlab script/function that can extract the value of each voxel?

Hi,
You can use the niftiread function to read the intensity values of the 4D spatiotemporal volume of the resting-fMRI into a numeric array.
