The niiT1vfa program enables a fast nonlinear least squares fit for T1 estimation using a robust and efficient version of the Levenberg-Marquardt minimization algorithm provided by a derivative solver in the Gnu Scientific Library (GSL, http://www.gnu.org/software/gsl/). Input data are variable flip angle (VFA) '.nii' data and (optionally) a processed actual flip angle imaging (AFI) 'nii' data set containing the flip angle (FA) distribution resulting from the prescribed AFI flip angle.
