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.

Thomas
