cortex.surfinfo.tissots_indicatrix(outfile, sub, radius=10, spacing=50)[source]

Compute a Tissot’s indicatrix for the given subject and save the result to a file. This involves randomly filling in discs of fixed geodesic radius on the fiducial surface.

See’s_indicatrix for more info.


Path where the indicatrix map will be saved.


Subject in the pycortex database for whom the indicatrix will be computed.

radiusfloat, optional

The geodesic radius of each disc in mm. Default 10.

spacingfloat, optional

The minimum distance between disc centers in mm. Default 50.
