RE: freesurfer_annot_to_gifti files DataType
Hi, in the case of the annotation file lh.aparc.a2009s.gii, the
data is RGBA values, which are unsigned, so technically i suppose
UINT32 is the accurate data type. however, it appears the
fact that UINT32 is not one of the required gifiti datatypes means
that it probably should be defined as INT32. i'm not sure
what to do at this point, as an argument could be made either which
should change: either UINT32 is added as a valid datatype
(thus making the freesurfer_annot valid), or freesurfer should
change the datatype for annot labels to INT32. maybe you
have thoughts on this. in any case, it gets interpreted as an
RGBA value, so it doesnt really matter.
