Usage

nifti2.write.extensions(fh, extensions, endian = "little")

Arguments

fh	filehandle, a connection to a NIFTI v2 file, positioned at the first byte after the fixed-size header (i.e., where the extension flag bytes go).
extensions	list of header extensions, see nifti2.extension. An empty list writes the extension flag for 'no extensions present'.
endian	character string, the endianness of the file, either 'little' or 'big'.

Value

integer, the number of bytes written (the extension flag bytes plus all extensions). The data must start at ⁠544 + <return value>⁠.
