Data and scripts are available to allow prediction of location V1 on a Freesurfer subject based on a probabilistic atlas. See the paper for details, and the README link for instructions on how to install the data (V1_average-1.1.tgz). See also BrodmannAreaMaps.  * [[https://surfer.nmr.mgh.harvard.edu/ftp/articles/hinds2008accurate.pdf|Accurate prediction of V1 location from cortical folds in a surface coordinate system]], Hinds, O.P., N.

{{{
recon-all -s subjid -label-v1
}}}

This will output:

 * <subjid>/label/?h.v1.prob.label - contains stat values
 * <subjid>/label/?h.v1.predict.label - thresholded

Note: This requires the subject found in $FREESURFER_HOME/subjects/V1_average to be located (symlinked or copied) in your $SUBJECTS_DIR.

See also BrodmannAreaMaps.

Note: To adjust the display to account for the probabilities in the label in tksurfer, try going to Tools->Label->Threshold Selected Label, then choose a threshold between 0 and 1.

V1 Atlas

To create these label: 

recon-all -s subjid -label-v1

This will output:

  • <subjid>/label/?h.v1.predict.label - thresholded

Note: This requires the subject found in $FREESURFER_HOME/subjects/V1_average to be located (symlinked or copied) in your $SUBJECTS_DIR.
