neuRosim: Functions to Generate fMRI Data Including Activated Data, Noise Data and Resting State Data

Share:

The package allows users to generate fMRI time series or 4D data. Some high-level functions are created for fast data generation with only a few arguments and a diversity of functions to define activation and noise. For more advanced users it is possible to use the low-level functions and manipulate the arguments.
