Write header and data to a file in NIFTI v2 format.

Usage

write.nifti2(filepath, niidata, niiheader = NULL, extensions = NULL)

filepath: the file to write. The extension should be '.nii' or '.nii.gz'.
niidata: array of numeric or integer data, with up to 7 dimensions. Will be written to the file with the datatype and bitpix specified in the 'niiheader' argument.
niiheader: an optional NIFTI v2 header that is suitable for the passed 'niidata'. If not given, one will be generated with ni2header.for.data.
extensions: optional list of NIFTI v2 header extensions to write between the header and the data, each created with nifti2.extension. If left at NULL and the 'niiheader' has a field named 'extensions', that field is used, so that a header read with read.nifti2.header can be written back to a new file without losing its extensions. The 'vox_offset' field of the header is adapted if it is too small to fit the extensions, and the data is written directly after them.
