Hi Nick,
Note that surface and surface dataset answers will be
fairly slow in coming, now that Ziad is gone.
1) It seems that an attribute of the read dataset (the
binary aspect) is stored for the INDEX_LIST upon read,
and that overrides the request to write it as text.
While there options to ponder regarding that, let me
suggest using simply 3dcopy (or other 3d* programs),
but with the AFNI_NIML_TEXT_DATA env var set to YES:
3dcopy -DAFNI_NIML_TEXT_DATA=Y dset.gii dset.niml.dset
2) I will look into that.
Out of curiosity, how did you even notice this? Did
you encounter software that cares?
