interfaces.mrtrix3.connectivity¶
BuildConnectome¶
Wraps the executable command tck2connectome.
Generate a connectome matrix from a streamlines file and a node parcellation image
Example¶
>>> import nipype.interfaces.mrtrix3 as mrt
>>> mat = mrt.BuildConnectome()
>>> mat.inputs.in_file = 'tracks.tck'
>>> mat.inputs.in_parc = 'aparc+aseg.nii'
>>> mat.cmdline
'tck2connectome tracks.tck aparc+aseg.nii connectome.csv'
>>> mat.run()
Inputs:
[Mandatory]
in_file: (an existing file name)
input tractography
argument: ``%s``, position: -3
out_file: (a file name, nipype default value: connectome.csv)
output file after processing
argument: ``%s``, position: -1
[Optional]
in_parc: (an existing file name)
parcellation file
argument: ``%s``, position: -2
nthreads: (an integer (int or long))
number of threads. if zero, the number of available cpus will be
used
argument: ``-nthreads %d``
vox_lookup: (a boolean)
use a simple voxel lookup value at each streamline endpoint
argument: ``-assignment_voxel_lookup``
search_radius: (a float)
perform a radial search from each streamline endpoint to locate the
nearest node. Argument is the maximum radius in mm; if no node is
found within this radius, the streamline endpoint is not assigned to
any node.
argument: ``-assignment_radial_search %f``
search_reverse: (a float)
traverse from each streamline endpoint inwards along the streamline,
in search of the last node traversed by the streamline. Argument is
the maximum traversal length in mm (set to 0 to allow search to
continue to the streamline midpoint).
argument: ``-assignment_reverse_search %f``
search_forward: (a float)
project the streamline forwards from the endpoint in search of
aparcellation node voxel. Argument is the maximum traversal length
in mm.
argument: ``-assignment_forward_search %f``
metric: ('count' or 'meanlength' or 'invlength' or 'invnodevolume' or
'mean_scalar' or 'invlength_invnodevolume')
specify the edge weight metric
argument: ``-metric %s``
in_scalar: (an existing file name)
provide the associated image for the mean_scalar metric
argument: ``-image %s``
in_weights: (an existing file name)
specify a text scalar file containing the streamline weights
argument: ``-tck_weights_in %s``
keep_unassigned: (a boolean)
By default, the program discards the information regarding those
streamlines that are not successfully assigned to a node pair. Set
this option to keep these values (will be the first row/column in
the output matrix)
argument: ``-keep_unassigned``
zero_diagonal: (a boolean)
set all diagonal entries in the matrix to zero (these represent
streamlines that connect to the same node at both ends)
argument: ``-zero_diagonal``
args: (a unicode string)
Additional parameters to the command
argument: ``%s``
environ: (a dictionary with keys which are a bytes or None or a value
of class 'str' and with values which are a bytes or None or a
value of class 'str', nipype default value: {})
Environment variables
Outputs:
out_file: (an existing file name)
the output response file
LabelConfig¶
Wraps the executable command labelconfig.
Re-configure parcellation to be incrementally defined.
Example¶
>>> import nipype.interfaces.mrtrix3 as mrt
>>> labels = mrt.LabelConfig()
>>> labels.inputs.in_file = 'aparc+aseg.nii'
>>> labels.inputs.in_config = 'mrtrix3_labelconfig.txt'
>>> labels.cmdline
'labelconfig aparc+aseg.nii mrtrix3_labelconfig.txt parcellation.mif'
>>> labels.run()
Inputs:
[Mandatory]
in_file: (an existing file name)
input anatomical image
argument: ``%s``, position: -3
out_file: (a file name, nipype default value: parcellation.mif)
output file after processing
argument: ``%s``, position: -1
[Optional]
in_config: (an existing file name)
connectome configuration file
argument: ``%s``, position: -2
lut_basic: (a file name)
get information from a basic lookup table consisting of index / name
pairs
argument: ``-lut_basic %s``
lut_fs: (a file name)
get information from a FreeSurfer lookup table(typically
"FreeSurferColorLUT.txt")
argument: ``-lut_freesurfer %s``
lut_aal: (a file name)
get information from the AAL lookup table (typically
"ROI_MNI_V4.txt")
argument: ``-lut_aal %s``
lut_itksnap: (a file name)
get information from an ITK - SNAP lookup table(this includes the
IIT atlas file "LUT_GM.txt")
argument: ``-lut_itksnap %s``
spine: (a file name)
provide a manually-defined segmentation of the base of the spine
where the streamlines terminate, so that this can become a node in
the connection matrix.
argument: ``-spine %s``
nthreads: (an integer (int or long))
number of threads. if zero, the number of available cpus will be
used
argument: ``-nthreads %d``
args: (a unicode string)
Additional parameters to the command
argument: ``%s``
environ: (a dictionary with keys which are a bytes or None or a value
of class 'str' and with values which are a bytes or None or a
value of class 'str', nipype default value: {})
