Hi,
I'm trying to upload the Tiff file of a CT scanning brain skull to afni. Before that, I reformat the tiff file into dicom file in Matlab using dicomwrite function.
However when I use afni to read the dicom file for futher processing, afni cannot read them properly let alone to save them. I'm using Dimon -gert_create_dataset function.

I've attached the warning from the afni.

Thank you very much for your help.
