Hi everyone,
I have two questions regarding FreeSurfer and FSL interoperation and it
would be great if someone could help.
1) When displaying subject-level FSL FEAT data onto the FS volume using the
command
"tkmedit blobby orig.mgz lh.white -overlay ./featdir/stats/zstat1.nii.gz
-overlay-reg featdir/reg/freesurfer/anat2exf.register.dat fthresh 1.3 -fmid
2.3 -fslope 1? (mentioned on
http://www.fmrib.ox.ac.uk/fsl/freesurfer/index.html)
What p-value does the threshold of 1.3 correspond to? Is it a zscore?
2) What would be the best way to display FSL group-level FEAT data (zstats)
onto the FreeSurfer surface?
As far as I understand, the FSL and FreeSurfer Interoperation website
explains how to display subject level-feat on the surface. For the
group-level data, it only explains how to run group-level analyses using
mri_glmfit based on lower-level FSL FEAT directories.
Is there a way to directly map the zstats from FSL group-level analyses onto
the FreeSurfer surface?
Thanks in advance for the help!
Nicole
