writeVolume-methods: Generic function to write a 3D image volume to disk

In neuroim: Data Structures and Handling for Neuroimaging Data

Description

Generic function to write a 3D image volume to disk

Usage

writeVolume(x, fileName, format, dataType)

## S4 method for signature 'BrainVolume,character,missing,missing'
writeVolume(x, fileName)

## S4 method for signature 'ClusteredBrainVolume,character,missing,missing'
writeVolume(x,
  fileName)

## S4 method for signature 'BrainVolume,character,character,missing'
writeVolume(x, fileName,
  format)

## S4 method for signature 'BrainVolume,character,missing,character'
writeVolume(x, fileName,
  dataType)

Arguments

x	an image object, typically a BrainVolume instance.
fileName	output file name
format	file format string. Since "NIFTI" is the only currently supported format, this parameter can be safely ignored and omitted.
dataType	output data type, If specified should be a character vector of: "BINARY", "UBYTE", "SHORT", "INT", "FLOAT", "DOUBLE". Otherwise output format will be inferred from R the datatype of the image.

Details

The output format will be inferred from file extension.

The output format will be inferred from file extension. writeVolume(x, "out.nii") outputs a NIFTI file. writeVolume(x, "out.nii.gz") outputs a gzipped NIFTI file.

No other file output formats are currently supported.

Examples

bvol <- BrainVolume(array(0, c(10,10,10)), BrainSpace(c(10,10,10), c(1,1,1)))
## Not run: 
writeVolume(bvol, "out.nii")
writeVolume(bvol, "out.nii.gz")

## End(Not run)
