this a basic question. in my code to read-in a .gii file, i do this:

gifti_image* image = gifti_read_image (fname, 0);

giiDataArray* coords = gifti_find_DA
(image, NIFTI_INTENT_POINTSET, 0);

giiDataArray* faces = gifti_find_DA
(image, NIFTI_INTENT_TRIANGLE, 0);


but when i look at the coords and faces arrays in debugger, the 'data' field is null. this happens when reading in the caret data, or the vistrails data.

i am probably just not doing something simple. is reading the data array an extra step? i can't seem to figure this out from the example files.

Hi Nick,

Yeah, in the call:

gifti_read_image (fname, 0);

that second parameter is a flag for whether to read the data. So pass 1, instead.

thanks. the answer was right there in front of me. kind of like looking for keys and not checking your pocket first.
