Predicts the value of the attenuation signal, according to the HYDI-DSI representation retrieved with the function atti2hydidsi, for a set of desired q-space locations specified by directions gi and b-values bi
eapfile | A regular sampling of the positive, unit mass Ensemble Average Propagator estimated with atti2hydidsi. To interpret this sampling, the following five input arguments (as returned by atti2hydidsi) are mandatory: |
dtifile | The estimated tensor model at each voxel. |
latticefile | The radii of the lattice at each voxel. This is useful in case this parameter is automatically determined instead of fed as an input argument. |
Qxfile,Qyfile,Qzfile | The estimated bandwidths of the q-space signal along each dimension. They are necessary to interpret the computed eap. Besides, you must provide the q-space points where the signal representation will be evaluated. THESE POINTS ARE NOT NECESSARILY THE SAME (BUT MIGHT BE) AS THOSE USED TO CALL atti2hydidsi: |
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 attenaution signal predicted at each voxel |
varargin | Optional arguments passed as -name value pairs (e.g. -wlsit 5). |
