Hi Susan, you can't use func2roi-sess. You'll have to put together some commands, but it should not be too hard, something like
mri_segstats --i lh.cope2.nii --slabel subjectname lh your.label --mask lh.zstat1.nii --maskthresh 2 --masksign abs --o sum.dat
where zstat1 is your all/nothing contrast sampled onto the surface and cope2 is some other contrast sampled on the surface. You can do this for each subject, then run asegstats2table giving it paths to all of your sum.dat files

Hi,
I am hoping do a surface-based functional ROI analysis on subject-specific ROIs that are both defined structurally and are masked by an all/nothing functional contrast. func2roi-sess seems perfect for this except that my data are not in an FS-FAST data/analysis structure, but are instead pre-processed and preliminarily analyzed using FSL and mapped to the surface using reg-feat2anat.
Is there any way to pass my original analysis into func2roi-sess? I tried using:
func2roi-sess -roidef LH_ant_STG_soundthresh2 -analysis 1012_Run4_featFULLrev.feat/stats/zstat4.nii.gz -anatlabel lh_ant_STG -maskcontrast 1012_Run4_featFULLrev/stats/zstat16.nii.gz -maskthreshold 2 -s 1012 -d
but get "ERROR: cannot find any sessions."
Or is there another tool more appropriate for what I am trying to do? I am looking at mri_segstats, but my hand-drawn ROIs (drawn on fsaverage in tksurfer and morphed to each subject using label_2_label) are in .label format and are on the surface.
Thanks in advance for and advice or suggestions.
