Hey, no worries at all! These things happen and I completely understand. What matters is that your system is up and running again. Take the time you need to get everything sorted. Looking forward to your updates when you’re ready. Cheers!

Hi,
The good news is that I was able to reproduce your behavior. The issue is not in dcm2niix but in the operations that QuNex does before the actual conversion. It seems like your dataset confuses QuNex in a weird way. The bad news is that I do not have a fix yet. I will keep you posted, we will try to fix this and integrate in our next release, which should be first half of May.
If this is something that is super pressing for you, a tedious workaround would be to convert relevant images to nii manually, convert everything to a BIDS structure and then onboard with import_bids.

Hi, Jure
I’m currently analyzing and processing the Siemens data; the processing of the UIH data is not super pressing.
I am very curious about what happened in this step and look forward to your solution. Good luck!

We coded a fix for this. It seems like UIH dicoms have a slightly different structure which confused QuNex. Before converting DICOM => NII, QuNex takes a look at all the DICOMs in the import folder/archive and tries to group them in images. As in your case this grouping is already done via subfolders, we added a flag to the import_dicom command called --existing_structure. This flag will simply assume that images are already grouped into folders and QuNex will not try to do its automated grouping. This will be released with the next version (most likely in mid May).
