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.
