getmask-methods: Methods for Function 'getmask' in Package 'dti'

In neuroconductor/dti: Analysis of Diffusion Weighted Imaging (DWI) Data

Description

Create a mask containing voxel inside the head

Usage

## S4 method for signature 'dtiData'
getmask(object, level = NULL, prop = 0.4, size = 3)

Arguments

object	an object of class "dtiData"
level	S0 intensity value to be used to discriminate between voxel inside and outside the brain. A good value of level may be determined using method sdpar in advance.
prop	proportion of voxel in test area with s0 value larger than level needed to decide for a voxel inside the brain
size	size of a cube defining a test area

Value

The function returns an object of class dtiData.

Methods

obj = "ANY"

Returns a warning

obj = "dtiData"

Create a mask containing voxel inside the head

obj = "array"

Create a mask containing voxel inside the head
