(value: 0) --xml Produce xml description of command line arguments (value: 0) --echo Echo the command line arguments (value: 0) --debug debug (value: 0) --elecnumber Number of stored gradient by electrostatic energy minimization. (value: -1) --tessorder Tessellation order for UNIFORM random type. (value: -1) --randomtype Random Type to rotate the given diffusion parameter in voxels. If UNIFORM is used, then the uniform orientation is randomly generated or from --tessorder or --elecnumber if one of them is set. (value: FIXED) --outputdwitype <4D|4DALL|EACHSHELL> Output DWI type. (value: 4DALL) --peaks Maximal number of peaks for output peak file. (value: 4) --tau Used for calculating q values from b values. The default value is set so that 4*pi^2*tau=1. (value: 0.0253303) --snr Signal-to-Noise Ratio. Conflicts with noisesigma. (value: 0) --noisesigma Noise level. Conflicts with snr. (value: 0) --b0scale The value of b0 image. (value: 1) --rvalues > R values for different shells. Each shell uses the same orientations specified with rgradients. Conflicts with rfile. --rfile Text file that contains the R values. The number of entries should be consistent with the orientations specified with rgradients. --rorientations Text file that contains the orientations for sampling in the R-space. --bvalues > B values for different shells. Each shell uses the same orientations specified with qgradients. Conflicts with bfile. --bfile Text file that contains the B values. The number of entries should be consistent with the orientations specified with qgradient. Conflicts with bvalues. --qorientations Text file that contains the gradient orientations of the data. --outb0 Output B0 image. --peaktype Peak Type. XYZV: peak direction vector (x,y,z) + peak magnitude v; XYZ: peak direction vector; NXYZV: number of peaks + peak direction vectors + peak magnitudes; NXYZ: number of peaks + peak direction vectors. (value: XYZV) --outmsd Scalar image that will contain the mean squared displacement (MSD) probability map. --outrto Scalar image that will contain the return-to-origin (RTO) probability map. --outpeak Vector image that will contain the ground truch of peaks. --outeap Vector image that will contain the EAP field. --outodf Vector image that will contain the ODF field. --outdwi Vector image that will contain the DWI field. --size > Image size. (value: 1,1,1) --modeltype Type of input diffusion parameters. (value: TENSOR_SPHERICAL) --params > diffusion parameters. --, --ignore_rest Ignores the rest of the labeled arguments following this flag. --version Displays version information and exits. -h, --help Displays usage information and exits.
