mvpa2.datasets.base.mask_mapper(mask=None, shape=None, space=None)

Factory method to create a chain of Flatten+StaticFeatureSelection Mappers


mask : None or array

an array in the original dataspace and its nonzero elements are used to define the features included in the dataset. Alternatively, the shape argument can be used to define the array dimensions.

shape : None or tuple

The shape of the array to be mapped. If shape is provided instead of mask, a full mask (all True) of the desired shape is constructed. If shape is specified in addition to mask, the provided mask is extended to have the same number of dimensions.
