retrieveNifti: Obtain an internal NIfTI representation of an object

Description

This function converts filenames, arrays and other image classes into an object of class "internalImage".

Usage

1
retrieveNifti(object)

Arguments

object

Any suitable object (see Details).

Details

If the object has an internal NIfTI pointer, that will be retrieved directly. Otherwise, if it is a string, it will be taken to be a filename. If it looks like a "nifti" object (from package oro.nifti), or an "MriImage" object (from package tractor.base), a conversion will be attempted. A list will be assumed to be of the form produced by dumpNifti. Finally, a numeric array or matrix will be converted using default image parameters.

Value

An internal image.
