I am conducting cortical thickness analyses between hundreds of individuals for a study we are conducting. I was getting this error

Unrecognized sub-option flag 'annot_outline'. and so I tried to do the group analysis tutorial and input the command from the end of it (please see command below) but still got the same error. Freeview would open but it would not show any images. Could you help me to resolve this issue please? Also, what does it mean when it spits out invalid drawable?

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 Thank you so much for your help! Claire
