cortex.utils.get_vox_dist

cortex.utils.get_vox_dist(subject, xfmname, surface='fiducial', max_dist=inf)

Get the distance (in mm) from each functional voxel to the closest point on the surface.

Parameters:

subjectstr

Name of the subject

xfmnamestr

Name of the transform

max_distnonnegative float, optional

Limit computation to only voxels within max_dist mm of the surface. Makes computation orders of magnitude faster for high-resolution volumes.

Returns:

distndarray (z, y, x)

Array with the same shape as the reference image of xfmname containing the distance (in mm) of each voxel to the closest point on the surface.

argdistndarray (z, y, x)

Array with the same shape as the reference image of xfmname containing for each voxel the index of the closest point on the surface.
