If you have the original DICOM files, then Dimon has different options for sorting via -dicom_org.
If you try that, start by including "-save_details DET", and feel free to send me the DET* text files via email.
But I don't actually see why you would want the files in the order slice0(TE0, TE1,..., TE15), slice1(TE0, TE1,..., TE15),...
To be sure, currently the first apparent "volume" (in the afni GUI, say) is all slice 0, is that right? That would seem like the thing to fix. But the wording has me a little confused.
