generateIRData

The function generates IR MRI example data for specified parameters

 utililities 

Implementation of methods for estimation of quantitative maps
from Multi-Parameter Mapping (MPM) acquisitions (Weiskopf et al. (2013)
<doi:10.3389/fnins.2013.00095>) and analysis of Inversion Recovery MRI data.
Usage of the package is described in
