MRtrix3 provides a set of tools to perform various advanced diffusion MRI analyses, including constrained spherical deconvolution (CSD), probabilistic tractography, track-density imaging, and apparent fibre density - mrtrix3/connectomestats.rst at 3.0.3 · MRtrix3/mrtrix Standard options¶-info display information messages.-quiet do not display information messages or progress status; alternatively, this can be achieved by setting the MRTRIX_QUIET environment variable to a non-empty string.-debug display debugging messages.-force force overwrite of output files (caution: using the same file as input and output might cause unexpected behaviour) The command will generate the same number of track files as there are nodes in the parcellation: one each for the streamlines connecting node 15 to every other node; i.e. from_15_to_1.tck, from_15_to_2.tck, from_15_to_3.tck, etc.. Because the -keep_self option is specified, file from_15_to_15.tck will also be generated. By default, the metric of connectivity quantified in the connectome matrix is the number of streamlines; or, if tcksift2 is used, the sum of streamline weights via the -tck_weights_in option. Use of the -out_assignments option is recommended as this enables subsequent use of the connectome2tck command.

  2. Options¶-wbft tracks provide a whole-brain fibre-tracking data set (of which the input track file should be a subset), to improve the estimate of fibre bundle volume in the presence of partial volume-afd_map image output a 3D image containing the AFD estimated for each voxel.-all_fixels if whole-brain fibre-tracking is NOT provided, then if multiple fixels within a voxel are traversed by the.
  3. Intensity normalisation is performed by optimising the voxel-wise sum of all tissue compartments towards a constant value, under constraints of spatial smoothness (polynomial basis of a given order). Different to the Raffelt et al. 2017 abstract, this algorithm performs this task in the log-domain instead, with added gradual outlier rejection.

Network-based representations have introduced a revolution in neuroscience, expanding the understanding of the brain from the activity of individual regions to the interactions between them. This augmented network view comes at the cost of high dimensionality, which hinders both our capacity of deciphering the main mechanisms behind pathologies, and the significance of any statistical and/or.

This should be supplied as a 4xN text file with each line is in the format [ X Y Z b ], where [ X Y Z ] describe the direction of the applied gradient, and b gives the b-value in units of s/mm^2

connectomestats [options] input algorithm design contrast output. input: a text file listing the file names of the input connectomes; algorithm. As raised on the forum. We no longer have the authority to attempt to change the name of a published method, given the duration of time since its publication, our generally pessimistic outlook on its performance, and the subtlety of our criticism of the existing name; so we'll be sticking to this name from now on

Options¶-power exp specify exponent to use for repulsion power law (default: 1). This must be a power of 2 (i.e. 1, 2, 4, 8, 16, ).-niter num specify the maximum number of iterations to perform (default: 10000).-restarts num specify the number of restarts to perform (default: 10).-unipolar optimise assuming a unipolar electrostatic repulsion model rather than the bipolar model normally. Description¶. This application attempts to remove Gibbs ringing artefacts from MRI images using the method of local subvoxel-shifts proposed by Kellner et al. (see reference below for details). This command is designed to run on data directly after it has been reconstructed by the scanner, before any interpolation of any kind has taken place. Matrix Animation and Polar Decomposition.

The output is a key-value text file containing: scaling: vector of 3 scaling factors in x, y, z direction.
