cortex.surfinfo.tissots_indicatrix¶
- 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 https://en.wikipedia.org/wiki/Tissot’s_indicatrix for more info.
- Parameters:
- outfilestr
Path where the indicatrix map will be saved.
- substr
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.
