using FS-FAST I have obtained a map reporting

- Red_positive cluster shows difference for FC of group A > FC of group B

- Blue_negative cluster shows difference for FC of group B < FC of group A

Because I would like to extract the value of cortical thickness from each cluster, I have saved using tksurfer the ROI.label of each cluster (Red_positive.label and Blue_negative.label)

Please note that each cluster was thresholded

+ 1.3 Red_positive.label

- 1.3 Blue_negative.label

Next, I have extracted the thickness of each cluster.

mri_label2label --srcsubject Subj01 --srclabel ROI.label --trgsubject Subj01 --trglabel Subj01/label/ROI.label --hemi lh --regmethod surface

mris_anatomical_stats -l Subj01/label/ROI.label -b Subj01

When applied the mri_anatomical_stats to blu cluster (Blue_negative.label), this error occurs:

mris_anatomical_stats -l Subj01/ROI_neg.label -b Subj01 lh

limiting computations to label /Subj01/label/ROI_neg.label.
