BrainObj.add_activation(self, data=None, vertices=None, smoothing_steps=5, file=None, hemisphere=None, hide_under=None, n_contours=None, cmap='viridis', clim=None, vmin=None, vmax=None, under='gray', over='red')[source][source]¶ Add activation to the brain template.
This method can be used for :
Add activations to specific vertices (data and vertices)
Add an overlay (file input)
- Parameters
- dataarray_like | None
Vector array of data of shape (n_data,).
- verticesarray_like | None
Vector array of vertex indices of shape (n_vtx). Must be an array of integers. If hemisphere is ‘left’ or ‘right’ indexation is done with respect to the specified hemisphere.
- smoothing_stepsint | 20
Number of smoothing steps (smoothing is used if n_data < n_vtx). If None or 0, no smoothing is performed.
- filestring | None
Full path to the overlay file. Can either be a nii.gz or gii file.
- hemisphrere{None, ‘both’, ‘left’, ‘right’}
The hemisphere to use to add the overlay. If None, the method tries to infer the hemisphere from the file name.
- hide_underfloat | None
Hide activations under a certain threshold.
- n_contoursint | None
Display activations as contour.
- cmapstring | ‘viridis’
The colormap to use.
- climtuple | None
The colorbar limits. If None, (data.min(), data.max()) will be used instead.
- vminfloat | None
Minimum threshold.
- vmaxfloat | None
Maximum threshold.
- understring/tuple/array_like | ‘gray’
The color to use for values under vmin.
- overstring/tuple/array_like | ‘red’
The color to use for values over vmax.
