Each of those individual files is relatively small and may only be a single slice each. So this might be the slices for only a single volume. Note that there are other kinds of diffusion scans (or scalar output from the scanner such as ADC maps) which are not compatible with DTI analysis. You could share some ( **!anonymized!** ) headers to get feedback, see instructions here:

> To make it easier to share the metadata with us for analysis, I’ve added the option to copy the metadata to clipboard. Could you please download the latest nightly version of Slicer now (if you downloaded Slicer yesterday or before then it is too old, it does not contain this feature yet), and then: Open DICOM browser Select the image that you want to load Check Advanced checkbox Click Examine button Click Metadata button Click Copy Metadata button Paste the copied text to any text editor Remo…

But probably the best option is to contact whoever is responsible for scanning these images to verify the scanning protocol.
