Dear Freesurfer team,
I messaged the team on my MPF map analysis and a suggestion was made that I
register the MPF maps on the T1 MPRAGE images. However, I did not acquire
MPRAGE but FLASH images.
Can I used those instead ? Again, I tried even using

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
olume you gave as input to recon-all. If you tell us which

alter the signal intensity or
contrast of the MPF images. Therefore, the registered MPF images still
reflect the macromolecular proton fraction of the brain tissue, which is
independent of the T1 values.
Just wanna confirm. This is from a colleague.

Dear Freesurfer Team,
I registered a Macromolecular Proton Fraction (MPF) map on T1 image using
multimodal registration in FSL and used freesurfer for the parcellation as
instructed by one of your colleagues. I want to really confirm that whether

Hello freesurfer team,
Please does Freesurfer have a function or a code for tissue Segmentation
just like in FSL that you can do tissue based segmentations into GM, WM and
CSF and also their partial volume segmentations?
Thank you.

Hi, freesurfer team
Is there a way to calculate the intensity of a voxel.Let say, I have a
voxel with coordinate 20, 30 and 34 and I wanna know the intensity of it.
Can it be done in freesurfer?

Dear fresurfer team,
Please I want to extract the intensity of a voxel 48, -56, -34. But my
voxel ranges of my image does not include negative values. Is there a way
to make the ranges cover these values.
Thanks 👍.
