At a first glance I'm not quite sure about the first error ( Unknown Value Representation ), but it seems to me that there's something wrong in the DICOM headers of that acquisition (or a part of it). Need to look into what the (0000, 0000) tag in DICOM is for - haven't seen this before. However, that smells like an actually corrupted DICOM file. Can you read all the DICOMS (or just their headers) in that acquisition with any software? And if so: What's the value for (0000, 0000)?
If we can figure out what's wrong in this case, that would be greatly appreciated!
The second error (KeyError) indicates that the DICOMS are missing a header field we expected to be there (Likely SeriesNumber). That's an issue with datalad-hirni indeed - we need to figure out how exactly to deal with missing ID fields of all kinds (which - for some fields of that kind - is likely to be caused by some anonymization procedure manipulating the DICOMS).
In this second case you could currently only manually build the specification file. Whether that's doable for you depends of course on how much you know about the acquisition and those specification files. I can help only with the second part. I'm working on a solution within hirni, but I can't promise how quickly I'll get that done.
Hi guys, We have successfully imported most of our acquisitions with datalad hirni-import-dcm. However, two acquisitions resulted in errors. The datalad hirni commands do not differ and with the DICOM acquisitions everything seems to be OK.

I would be grateful for any help.
