in_bundle in_fodf afd_mean_map
Compute the mean Apparent Fiber Density (AFD) and mean Radial fODF (radfODF)
maps along a bundle.
This is the "real" fixel-based fODF amplitude along every streamline
of the bundle provided, averaged at every voxel.
Please use a bundle file rather than a whole tractogram.
Formerly: scil_compute_fixel_afd_from_bundles.py
positional arguments:
in_bundle Path of the bundle file.
in_fodf Path of the fODF volume in spherical harmonics (SH).
afd_mean_map Path of the output mean AFD map.
options:
-h, --help show this help message and exit
--length_weighting If set, will weigh the AFD values according to segment lengths. [False]
--reference REFERENCE
Reference anatomy for tck/vtk/fib/dpy file
support (.nii or .nii.gz).
--sh_basis {descoteaux07,tournier07,descoteaux07_legacy,tournier07_legacy}
Spherical harmonics basis used for the SH coefficients.
Must be either descoteaux07', 'tournier07',
'descoteaux07_legacy' or 'tournier07_legacy' [['descoteaux07_legacy']]:
'descoteaux07' : SH basis from the Descoteaux et al.
MRM 2007 paper
'tournier07' : SH basis from the new Tournier et al.
NeuroImage 2019 paper, as in MRtrix 3.
'descoteaux07_legacy': SH basis from the legacy Dipy implementation
of the Descoteaux et al. MRM 2007 paper
'tournier07_legacy' : SH basis from the legacy Tournier et al.
NeuroImage 2007 paper.
-v [{DEBUG,INFO,WARNING}]
Produces verbose output depending on the provided level.
Default level is warning, default when using -v is info.
-f Force overwriting of the output files.
