I’m a new in neuroimaging and I have segmented Nifti structural MRI with SPM12 into grey matter. I got as result the file rwc1<original_filename> but I was wondering two things :
- What is the type of this file ? Is it Nifti like the original ?
- Most important question : Do the number in the MRI matrix correspond to the voxel intensities (like in the original) ? Or do they correspond to probability map ? I ask this because I heard about applying a mask on the original image to get the grey matter.
Thanks in advance
