cortex.surfinfo.bumpy_flatmap

cortex.surfinfo.bumpy_flatmap(outfile, subject, **kwargs)

Give the flatmap the relief of the cortical slab, and cache it.

Hemispheres with no flat surface get an array of zeros rather than an error.

Parameters:

outfilestr

Path where the offsets will be saved as an npz file.

subjectstr

Subject in the pycortex database whose flatmap gets the relief.

**kwargs

Passed to cortex.polyutils.FlatSlab.

Notes

Stored under bump_left and bump_right rather than left and right on purpose: get_surfinfo turns a file with the latter into a Vertex by concatenating them, which assumes one value per vertex and would mangle these three-component offsets.
