Module Description

Program title DTIAverage
Program description dtiaverage is a program that allows to compute the average of an arbitrary number of tensor fields (listed after the --inputs option) This program is used in our pipeline as the last step of the atlas building processing. When all the tensor fields have been deformed in the same space, to create the average tensor field (--tensor_output) we use dtiaverage. \n Several average method can be used (specified by the --method option): euclidian, log-euclidian and pga. The default being euclidian.
Program version 1.0.0

This program takes multiple inputs. Since 3D Slicer does not allow a user to give multiple inputs, this software is not really usable within Slicer. It is recommended to use it as a command line tool.

Quick Tour of Features and Use

A list panels in the interface, their features, what they mean, and how to use them.

  • I/O:
    • Inputs [----inputs] : List of all the tensor fields to be averaged
    • Averaged tensor field file name [----tensor_output] : Averaged tensor volume
  • Advanced options:
    • DTI double (do not use in 3D Slicer) [----DTI_double] : Tensor components are saved as doubles (cannot be visualized in Slicer) Default value: false
    • Verbose [----verbose] [-v]: produce verbose output Default value: 0
