I want to use the intensity of the macromolecular proton fraction (MPF). I want to compare the intensity of the MPF of the various brain regions or structures between two groups. I am not using the volumes. The MPF was registered on the T1 so does it mean that the intensity is from the MPF.

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.

External Email - Use Caution *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? _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://secure-web.cisco.com/1dzKa_STAYsTK1G2J9O29BFrJaMJvbTrDyznta6_o8bUWmO...
