Dear mailing list,

I am doing the group analysis freesurfer tutorial. When I try to open the significance map, I get the error message "unrecognized sub-opton flag 'overlay_threshold'. "

The command is freeview -f $SUBJECTS_DIR/fsaverage/surf/lh.inflated:annot=aparc.annot:annot_outline=1:overlay=lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/sig.mgh:overlay_threshold=4,5 -viewport 3d

I get the same error message doing the tutorial on my mac os x and on a linux, so I doubt there is a problem with the tutorial data. All files needed seem to be in the directory.

I very much appreciate any help

Best,
Vilde
