writes an array to a .img/.hdr pair in NIFTI format or to a .nii file

Description

Creates a .img/.hdr pair of files or a .nii file from a given array

Usage

f.write.nifti(mat,file,size,L,nii,path.out=NULL)

Arguments

mat	An array
file	The name of the file to be written, without .img or .hdr suffix
size	Specify the format of the .img file. Either "float" (for 4 byte floats) or "int" (2 byte integers) or "char" (1 byte integers).
L	if NULL, the list is created by the function, else it should be provided. This list contains the header part of a NIFTI image.
nii	should we write only one .nii file or a .hdr/.img pair of files
path.out	The path where to write the file (mandatory argument, even if the default value is NULL for backward compatibility)

Value

Nothing is returned

file<-"temp"
tmpdir <- tempdir()
f.write.nifti(a,file,size="float",nii=TRUE, path.out = tmpdir)
unlink(tmpdir) # tidy up
