Dear Freesurfer List,
I ran the script for predicting V1 location on the surface: http://surfer.nmr.mgh.harvard.edu/fswiki/V1
According to the paper, the output should be a probability map, but the script only seems to produce a label file: $SUBJECT_DIR/label/?h.v1.prob.label . When I load this file (it only loads as 'label') it is a binary label, with no probability values associated with it. That means it is a pretty generous description of predicted V1. How can I get probability values and trim it to, let's say, >80% probability?
Thanks for your input.

In tksurfer, try going to Tools->Label->Threshold Selected Label. Then choose a threshold between 0 and 1. doug

Hi Thomas,
there is a tksurfer menu item to transfer the label stat field to an overlay, and you can go from there.
cheers Bruce
