Get Vertices for an ROIΒΆ
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).
Out:
<Figure size 1960x1024 with 2 Axes>
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)
