mincIO.makeNewVolume-methods: Methods to create a new, empty 3D Minc volume object
In jnikelski/rmincIO: Package for reading and writing MINC2 files

Description Usage Arguments Value Author(s) See Also Examples

There exist 2 different ways to get an instantiated MincVolumeIO object: (1) create one as a result of loading a pre-existing minc volume, and (2) create an empty volume from scratch. This method deals with the second way.

## S4 method for signature 'character,numeric,numeric,numeric,missing,missing'
mincIO.makeNewVolume(filename,dimLengths,dimSteps,dimStarts,likeTemplate,likeFile)

## S4 method for signature 
## 'character,missing,missing,missing,character,missing'
mincIO.makeNewVolume(filename,dimLengths,dimSteps,dimStarts,likeTemplate,likeFile)

## S4 method for signature 
## 'character,missing,missing,missing,missing,character'
mincIO.makeNewVolume(filename,dimLengths,dimSteps,dimStarts,likeTemplate,likeFile)

`filename`	The filename of the minc volume to be created. The name is only placed into the MincInfo header. While no IO is actually performed as this time, the `mincIO.writeVolume` method will use this name at file creation time.
`dimLengths`	A vector of 3 integers specifying the number of elements in the x, y, and z dimensions (in that order)
`dimSteps`	A vector of 3 doubles specifying the step size of elements in the x, y, and z dimensions (also in that order)
`dimStarts`	A vector of 3 doubles specifying the start offsets of elements in the x, y, and z dimensions (yet again in that order)
`likeTemplate`	In order to facilitate volume creation, rather than specifying all of the above arguments, one can specify 1 of 3 volume templates whose characteristics are already known to the system. The 3 valid template names are: (1) `icbm152`, (2) `mni305linear`, and (3) `mni305PET`.
`likeFile`	One also has the option of specifying a “like” volume. The properties of the new volume shall then be set to match those of the “like” volume.

An instantiated, empty, MincVolumeIO object that has been initialized to zeros.
