.Peaks2MapsKernel¶
-
class
Peaks2MapsKernel
(resample_to_mask=True)[source]¶ Generate peaks2maps modeled activation images from coordinates.
- Parameters
resample_to_mask (
bool
, optional) – If True, will resample the MA maps to the mask’s header. Default is True.
-
get_params
(deep=True)[source]¶ Get parameters for this estimator.
- Parameters
deep (boolean, optional) – If True, will return the parameters for this estimator and contained subobjects that are estimators.
- Returns
params (mapping of string to any) – Parameter names mapped to their values.
-
set_params
(**params)[source]¶ Set the parameters of this estimator.
The method works on simple estimators as well as on nested objects (such as pipelines). The latter have parameters of the form
<component>__<parameter>
so that it’s possible to update each component of a nested object.- Returns
self
-
transform
(dataset, masker=None, return_type='image')[source]¶ Generate peaks2maps modeled activation images for each Contrast in dataset.
- Parameters
dataset (
nimare.dataset.Dataset
) – Dataset for which to make images.masker (img_like, optional) – Only used if dataset is a DataFrame.
return_type ({‘image’, ‘array’}, optional) – Whether to return a niimg (‘image’) or a numpy array. Default is ‘image’.
- Returns
imgs (
list
ofnibabel.Nifti1Image
ornumpy.ndarray
) – If return_type is ‘image’, a list of modeled activation images (one for each of the Contrasts in the input dataset). If return_type is ‘array’, a 2D numpy array (C x V), where C is contrast and V is voxel.
