Generating simulated activation maps
=====================================
.. currentmodule:: nipy.neurospin.utils.simul_2d_multisubject_fmri_dataset
The module :mod:`nipy.neurospin.utils.simul_2d_multisubject_fmri_dataset`
contains a function to create simulated 2D activation maps:
:func:`make_surrogate_array`. The function can position various
activations and add noise, both as background noise and jitter in the
activation positions and amplitude.
This function is useful to test methods.
Example
--------
.. plot:: neurospin/plots/surrogate_array.py
:include-source:
