Dear Doug and the Freesurfers, Ok, so is there a special filtered_func.nii generated from reg-feat2anat for each run or can I just use the feat?
When one does a cross-subject PPI in FSL and enter each run from each person, isn't everyone in a different space? How do you account for this when doing setting up the PPI feat?
Thanks. Michelle

Hi Freesurfers, I want to do a PPI in FSL FEAT using the V1 left and righ found generated in recon-all as seeds using:
I know for each subject I have to get a timecourse for my seeds fslmeants -i filtered_func.nii.gz -o my_timecourse.txt -m V1_mask.nii.gz
For each subject, I've run reg-feat2anat on my FEAT data from each of 4
runs.
I have 2 questions:
- Does it matter which run's FEAT I use for aseg2feat --feat featdir
--aseg aparc+aseg to generate the binary masks for my seeds?
don't you need to run it on each feat to get a time course for each run?
- Does fslmeants need a special registered filtered_func.nii.gz from
a cross-run GFEAT? If so, how do you specify it for this and then for actual PPI analysis in fsl?
Maybe I'm confused, but I thought you had to run it on the time course
data (which is not in the GFEAT).
