Given the coefficients of the MAP-MRI expansion, reconstruct the corresponding attenuation signal, according to the model described by Ozarslan et al:
Ozarslan E, Koay CG, Shepherd TM, Komlosh ME, Irfanoglu MO, Pierpaoli C, Basser PJ. "Mean apparent propagator (MAP) MRI: a novel diffusion imaging method for mapping tissue microstructure". Neuroimage. 2013 Sep; 78:16-32.
This function does the converse job of atti2mapl.
maplfile | The MAPL coefficients, where: K = (Nmax+2)(Nmax+4)(2*Nmax+3)/24 for some even integer Nmax>=0. |
dtifile | The estimated tensor model at each voxel. |
gifile | A string specifying the file containing the gradient directions. |
bifile | A string specifying the file containing the b-values. |
attifile | A string specifying the file to save the values reconstructed for the attenuations signal at each of the MxNxP voxels within the FOV. |
varargin | Optional arguments passed as -name value pairs (e.g. -wlsit 5). |
