[Neuroimaging] Reading a byte stream into nibabel

[Christopher Markiewicz]

Hi Valerie,

Assuming that it's not gzipped, you can do something like:

    from io import BytesIO
    from nibabel import FileHolder, Nifti1Image
    fh = FileHolder(fileobj=BytesIO(input_stream))
    img = Nifti1Image.from_filemap({'header': fh, 'image': fh})

If it is gzipped, adjust accordingly:

    from gzip import GzipFile
    fh = FileHolder(fileobj=GzipFile(fileobj=BytesIO(input_stream)))

Cheers,
Chris
