I want to use the intensity of the macromolecular proton fraction (MPF). I want to compare the intensity of the MPF between two groups.

It is whatever volume you gave as input to recon-all. If you tell us which statistics you want to regenerate for another volume we can tell you know what commands to run.

Hi,

 

Please I made an initial enquiry about using freesurfer for MPF maps. The feedback was that I register the MPF maps on their corresponding T1 images using multimodal registration. I used FSL to do the multimodal registration and then use recon-all in freesurfer.

Now I want to know what the intensity and the volume of the output in the aseg file represent. Is it the intensity of the MPF or the TI and MPF?
