Hello all
I am still having some trouble getting started on preprocessing of my ASL
data. Steve Smith has suggested that I do sub-TR timing-adjustment before a
subtraction analysis in FEAT. I wonder if anyone in the Martinos center has
expertise with this kind of analysis. If possible, I'd lik
Indeed - you don't just want to do pairwise subtraction Abi, it's
better to do sub-TR timing-adjustment on the tagged and control data
before subtraction - if you look in the latest version of FEAT in FSL
you'll see options for easy preprocessing of ASL data. You would then
be able to use t
We don't have an MC program. You can try running FSL's FLIRT or AFNI's
3dvolreg. As for analysis, you should be able run
mri_concat --paired-diff --mean inputaslvolume outputvolume
I've never actually tried it like this, but it should work.

Hi all
I have collected some raw Arterial Spin Labeling (ASL) data. I would like
to use freesurfer to create perfusion maps of this data. Is it possible to
take the raw data, motion correct it, perform a pairwise subtraction, and
then average all the subtractions to create a mean perfusion map?
