Class "dti"

Description

Basic description of Diffusion Weighted Image (DWI) data

Objects from the Class

Objects can be created by calls of the form new("dti", ...).

Slots

.Data:
Object of class "list" usually empty
btb:
Object of class "matrix" matrix of dimension c(6,ngrad) obtained from gradient directions.
ngrad:
Object of class "integer" number of gradients (including zero gradients)
s0ind:
Object of class "integer" index of zero gradients within sequence 1:ngrad
replind:
Object of class "integer" index (identifier) of unique gradient directions. Used to charactreize replications in the gradient design by identical indices. length is ngrad
ddim:
Object of class "integer" dimension of original image cubes. Integer vector of length 3.
ddim0:
Object of class "integer" dimension of subcube defined by xind, yind and zind.
xind:
Object of class "integer" index for subcube definition in x-direction
yind:
Object of class "integer" index for subcube definition in y-direction
zind:
Object of class "integer" index for subcube definition in z-direction
voxelext:
