write_vec-methods: Write a 4d image vector to disk

In bbuchsbaum/neuroim2: Data Structures and IO for Neuroimaging Data with an Emphasis on Functional Magnetic Resonance Imaging (FMRI)

Write a 4d image vector to disk

Description

Write a 4d image vector to disk

Usage

write_vec(x, file_name, format, data_type, ...)

## S4 method for signature 'LatentNeuroVec,character,missing,missing'
write_vec(x, file_name, nbit = FALSE, compression = 9, chunk_dim = NULL)

## S4 method for signature 'ROIVec,character,missing,missing'
write_vec(x, file_name)

## S4 method for signature 'NeuroVec,character,missing,missing'
write_vec(x, file_name)

## S4 method for signature 'NeuroVec,character,character,missing'
write_vec(
  x,
  file_name,
  format,
  nbit = FALSE,
  compression = 5,
  chunk_dim = c(10, 10, 10, dim(x)[4])
)

## S4 method for signature 'NeuroVec,character,missing,character'
write_vec(x, file_name, data_type)

Arguments

x	an image object, typically a NeuroVec instance.
file_name	output file name.
format	file format string. Since "NIFTI" is the only currently supported format, this parameter can be safely ignored and omitted.
data_type	the numeric 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.
...	extra args
nbit	set nbit compression
compression	compression level 1 to 9
chunk_dim	the dimensions of each chunk

Examples

bvec <- NeuroVec(array(0, c(10,10,10,10)), NeuroSpace(c(10,10,10,10), c(1,1,1)))
## Not run: 
write_vec(bvol, "out.nii")
write_vec(bvol, "out.nii.gz")
write_vec(bvec, "out.nii")
write_vec(bvec, "out.nii.gz")

## End(Not run)
