writeMRI: Write an MR Image

Description

Write an MR image into a file of different formats.

Usage

writeMRI(data, file, header, format)

Arguments

data

MRI data in a three dimensional array or four dimensional array with the forth dimension equal to 1.

file

the name of the image file to be written out.

header

the header file. For file of the "rawb.gz" format, header is NULL.

format

the format of the image file. Right now only the "Analyze", "NIfTI", and raw byte (unsigned with 1 byte per element in the byte stream) gzip formats are supported.

Value

• Nothing is returned.

Details

Header file is needed for the file of "Analyze" or "NIfTI" format. For details of the header files for "Analyze" format, see http://eeg.sourceforge.net/ANALYZE75.pdf. For details of the header files for "NIfTI" format and the comparison between the "Analyze" and "NIfTI" formates, see http://nifti.nimh.nih.gov/.

Files of "Analyze" format are written out through the function write.ANALYZE. An adapted version of write.NIFTI is used to write files of "NIfTI" format. Instead of ".nii", the adapted version writes data out into ".nii.gz" files to save space.
