Apologies, please ignore the other email response. I believe this should be tagged to the right thread (hopefully!) -----
Many thanks for the information, Doug! I will give it a go.
Actually, I would like to carry out the following analyses:
Get regional estimates of perfusion within a region of interest as defined by a significant cluster after mri_glmfit-sim. as well as other cortical regions that are connected to that cluster in terms of WM paths. Is it possible to do that in Freesurfer environment?
How can I do PVC for perfusion in ROIs? Will the -pv ppvol flag be crucial during the mri_segstats stage?
Thanks again for help.
Best Wishes, Elijah

No, not really. If you're not doing anything fancy (eg, just computing mean of tag-control) and mapping to the surface, it is easy enough to do (mri_concat --paired-diff --sum, then bbregister to register to the anat, then mri_vol2surf or mris_preproc to map to fsaverage, then mri_glmfit and mri_glmfti-sim. If you're trying to correct for decay, intensity gradients, etc, then no.

Hi Freesurfer Team,
Is there an ASL-friendly processing pipeline embedded in Freesurfer? Something like an equivalent to that of PetSurfer? Thanks.
Best Wishes, Elijah
