To create these label: {{{ 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
Accurate prediction of V1 location from cortical folds in a surface coordinate system, Hinds, O.P., N. Rajendran, J.R. Polimeni, J.C. Augustinack, G. Wiggins, L.L. Wald, H.D. Rosas, A. Potthast, E.L. Schwartz and B. Fischl (2008). NeuroImage 39:1585-1599.
To create these label:
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.
