Simulating data¶
Tools for easily simulating data, i.e. “placing” effects of certain strength and certain temporal and/or spatial extent into a brain.
fmrisim¶
A python module, part of the Brainiak package, that contains a set of functions necessary to produce realistic simulations of fMRI data for a single subject. Steps include haracterizing the signal and generating the noise model, which are then combined to simulate brain data.
