This page describes how to use the brain visualization filter inside Paraview:
For the plugin to compute the visualization, the following elements are required:
numpy
file that is generated with a command line tool form
the brain connectivity package, and that is described in the section Connectivity file from Nifti.The parameters exposed to the user by the plugin are shown in the picture below:
The meaning of the parameters are:
resolution
: indicates the edges resolution, ie. the number of intermediate steps a path
connecting two sites is divided into. The higher this number, the smoother the trajectory but also the
heavier the on-screen drawing,edge selection
: a range of edge indices on which the processing will be performed. Any edge falling
outside of this range is ignored in the visualization and the computation. This entry is ignored when
a cluster file is provided.edge file
: the absolute path of the file containing the definition of the topology,show edges
: if checked, the edges will be shownclusters file
: the absolute path to the file containing the results of the clustering.
This file contains a preprocessed version
of the clustering. If not present, a clustering of the selected edges will be computed during the visualization,
which may take some time. For offline computation of the clustering, see the corresponding section.nb_clusters
: indicates the number of desired clusters. This applies on the range of edges that has
been selected or the full range if no selection has been made, and is ignored if the clustering file
is
given.cluster index
: if given, a specific cluster to show on screen. All other clusters are discarded. The
edges that are in the specified cluster are also shown.hierarchy index
: the level of the hierarchy to which the cluster index applies.Note
The hierarchical part is not functional.
