/* TYPE OF DATA (acceptable values for datatype field):
---------------------------------------------------
Values of datatype smaller than 256 are ANALYZE 7.5 compatible.
Larger values are NIFTI-1 additions. These are all multiples of 256, so
that no bits below position 8 are set in datatype. But there is no need
to use only powers-of-2, as the original ANALYZE 7.5 datatype codes do.
The additional codes are intended to include a complete list of basic
scalar types, including signed and unsigned integers from 8 to 64 bits,
floats from 32 to 128 bits, and complex (float pairs) from 64 to 256 bits.
Note that most programs will support only a few of these datatypes!
A NIFTI-1 program should fail gracefully (e.g., print a warning message)
when it encounters a dataset with a type it doesn't like.
