Negating an image with math_img#
The goal of this example is to illustrate the use of the function
nilearn.image.math_img on T-maps.
We compute a negative image by multiplying its voxel values with -1.
from nilearn import datasets, plotting, image
Retrieve the data: the localizer dataset with contrast maps.
Multiply voxel values by -1.
