dtiIndices-methods: Methods for Function `dtiIndices' in Package `dti'

Description

The method creates estimates of the fractional anisotropy (FA) and relative anisotropy (RA) indices, the main directions of anisotropy and several statistics used for visualization.

Usage

## S3 method for class 'dtiTensor':
dtiIndices(object, mc.cores = setCores(,reprt=FALSE))

Arguments

object

Object of class "dtiTensor"

mc.cores

Number of cores to use. Defaults to number of threads specified for openMP, see documentation of package awsMethods. Our experience suggests to use 4-6 cores if available.

Value

An object of class "dtiIndices".
