Hello,
In the stable 3 environment, I ran the func2roi-sess command. This is what was included:
func2roi-sess -roidef dACC99_rh -analysis EMerror -anatlabel dACC-rh -maskcontrast ASevfix -maskframe 5 -maskthresh 0.0043648054 -masktail pos -maskmap sig -sf Subject_files/MTHFRn18-list -d $SUBJECTS_DIR
I then ran this summary generating command:
roisummary-sess -roidef dACC99_rh -analysis EMerror -sf Subject_files/MTHFRn18-list -d $SUBJECTS_DIR -sumfile $SUBJECTS_DIR/dACC999_rh.txt
I've viewed the summary file, and found that there are negative values listed for some of the conditions time points (e.g conditon 1, 2 sec after stimulus onset).
How can this be if I included the masktail pos flag? I thought that only captured positive activation.
If there is a way to solve this issue and capture only positive activation, please post when you can.
Thank you,
Dave Brohawn
