Patch

A patch is a saved section of flattened surface. Viewing patches switches the view to a flat 2D mode in which some of the controls don't work.

When making cuts and flattening a surface, you can then save out the resulting section of surface as a patch.

Loading Patches

Use the File->Patch->Load Patch... item to load a patch file.

Saving Patches

Use the File->Patch->Save Patch command to overwrite the original file, or File->Patch->Save Patch As... to save a new patch file in a new location.

-The occiput patch represents the occipital pole with a cut down the calcarine fissure. This cortical patch is particularly useful for displaying the results of visual experiments.


Select Make Occip Surface Cuts from the Subject Tools menu in csurf:

1. Make calcarine sulcus relaxation cut.
·  Select points (left-click) along the calcarine fissure beginning at the occipital pole and moving
anteriorly.
·  Open-line cut with CUTLINE (surfer tools).

2. Specify cutting plane.
·  Select three points (labeled 1, 2, and 3 below) to define the cutting plane, and a fourth point
(labeled 4 below) to specify which portion of the surface to keep (left-click).

3. Make the planar cut.
·  CUTPLANE button.

4. Save patch.
·  Specify the patch name in the patch field and press WRITE.
The default names for the occiput cortical surfaces are:
rh.occip.patch.3d
lh.occip.patch.3d
