Hi,
Try looking at the file README.attributes in the afni source code or at [
afni.nimh.nih.gov]. The file has plenty of information on the various header fields in AFNI including the warp fields.
Also, if you'd like to look at various chunks of the code, try our doxygen web page:
[
afni.nimh.nih.gov]
You can navigate through all the code there.
cheers,
