nilearn.surface.PolyMesh¶

class nilearn.surface.PolyMesh(left=None, right=None)[source]¶

A collection of meshes.

It is a shallow wrapper around the parts dictionary, which cannot be empty and whose keys must be a subset of {“left”, “right”}.

Added in version 0.11.0.

Parameters:

leftstr or pathlib.Path or nilearn.surface.SurfaceMesh or None, default=None: SurfaceMesh for the left hemisphere.
rightstr or pathlib.Path or nilearn.surface.SurfaceMesh or None, default=None: SurfaceMesh for the right hemisphere.

Attributes:

n_verticesint: number of vertices

__init__(left=None, right=None)[source]¶

n_vertices¶

to_filename(filename)[source]¶

Save mesh to gifti.

Parameters:

filenamestr or pathlib.Path: If the filename contains hemi-L then only the left part of the mesh will be saved. If the filename contains hemi-R then only the right part of the mesh will be saved. If the filename contains neither of those, then _hemi-L and _hemi-R will be appended to the filename and both will be saved.
