mvpa2.misc.surfing.volsurf.VolumeBasedSurface

class mvpa2.misc.surfing.volsurf.VolumeBasedSurface(vg)

A surface based on a volume, where every voxel is a node. It has the empty topology, meaning there are no edges between nodes (voxels)

Use case: provide volume-based searchlight behaviour. In that case finding neighbouring nodes is supposed to be faster using the circlearound_n2d method.

XXX make a separate module?

Methods

circlearound_n2d(src, radius[, metric])

Parameters:

vg: Volgeom.volgeom or str or NiftiImage :

volume to be used as a surface

Methods

circlearound_n2d(src, radius[, metric])

circlearound_n2d(src, radius, metric='euclidean')
