You have to specify an anatomical constraint that defines DLPFC. What you have done will not have anything to do with the DLPFC, it will average over all voxels with sig > 1.3 regardless of spatial location. The easiest thing to do is to draw a DLPFC label on fsaverage, then map it to each subject using mri_label2label, then specify this label to func2roi-sess with -anatlabel.

Hi all,

I am trying to use func2roi-sess to analyze functional ROI data for the left and right DLPFC, but these are not listed as labels on the FreeSurferColorLUT on http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI/FreeSurfer.... Do I need to create my own ROI labels for these?

I tried the command "func2roi-sess -roidef DLPFC -analysis fmcsm5_functionals -c Cond1v7 -s FB0011046AA -maskthresh 1.3 -maskmap sig.nii " which actually ran to completion and created a DLPFC folder in my subject file, but I really have no idea if this helps at all with my goal of, to quote my PI, "look at the dorsolateral prefrontal cortex ROI data, which will generate a single value for the average activation within the right or left DLPFC for each subject, during each condition".
