Get Vertices for an ROI¶
In this example we show how to get the vertices that are inside an ROI that was defined in the SVG ROI file (see /rois.rst).

import cortex # get vertices for fusiform face area FFA in subject S1 roi_verts = cortex.get_roi_verts('S1', 'FFA') # roi_verts is a dictionary (in this case with only one entry) ffa_verts = roi_verts['FFA'] # this includes indices from both hemispheres # let's create an empty Vertex object and fill FFA ffa_map = cortex.Vertex.empty('S1', cmap='plasma') ffa_map.data[ffa_verts] = 1.0 cortex.quickshow(ffa_map)
