yes, i am using gifti_find_DA to locate data arrays of particular intent codes. my question is what to do if a file has multiple intent codes of the types _NONE, _SHAPE and _TIME_SERIES. if it does has multiple DataArrays with these differing intent codes, then it is impossible to know which one to read when it is desired to load 'overlay' data. currently freesurfer just looks for all data arrays of that type and loads any and all of those three in a our internal time series array. but the possibility exists of having a mix of intent code data types in this list.
