Missing information JSON files

,
1

Hello everyone!
I ran a draft of my BIDS dataset through the BIDS validator and I got several errors. While trying to fix those, I noticed that whatever I put in my configuration files, it doesn’t change anything. For example, it indicates “error: SIDECAR_KEY_REQUIRED (TaskName)”. I updated my configuration file and made sure that the TaskName sidecar is in there. But when I check my json files after re-running dcm2bids, it still doesn’t include the TaskName. Similarly, the fieldmap json files do not include the IntendedFor information, even though I included this in the configuration file just like explained in the dcm2bids documentation. I would really appreciate it if someone could check my scripts and configuration files to see why exactly this is happening. Thank you!

dcm2bids version: 3.2.0
dcm2niix version: v1.0.20240202

Hi @ankevr97,

Please refer to the documentation (Create a config file - dcm2bids documentation). You misspelled the sidecar_changes field.

Best,
Steven

That is such a stupid mistake. Thank you so much, Steven!

Getting stuck because of a typo: we’ve all been there! Welcome to the club! :stuck_out_tongue_winking_eye:

I don’t understand why the JSON file I obtained using dcm2ii is constantly reported as "A data file’s JSON sidecar is missing a key listed as required. If that’s the case, does it mean that it’s not recommended to use the dcm2ii tool package to obtain JSON files?

6

no: it just means that the dcm2ii cannot extract ALL the metadata required by BIDS from the DICOM file.

for example for functional MRI, BIDS require the name of the task to be in the metadata: AFAIK this metadata does not exist in the dicom file has to be added during the conversion process which is why you should probably use a BIDS converter rather dicom2nii if you want to get a valid BIDS dataset in the end

@haixia_mao dcm2niix converts all the known mappings between a DICOM file and the BIDS standard. It will fail to populate a tag if the DICOM does not include this parameter or if no one has documented how to extract that key from a DICOM. The dcm2niix DICOM → BIDS web page provides the mappings. Manufacturer specific pages report additional details, for example noting the missing keys in Philips MR.

If you are missing BIDS fields:

  1. Make sure you are using the latest version of dcm2niix - we are cnotinuously improving our knowledge of how manufacturers store sequence details.
  2. Make sure that you are using source DICOM images that have not been stripped of required tags (e.g. over zelaous anonymization of DICOMs).
  3. Work with the manufacturer representative affiliated with your instrument (e.g. Siemens Research Collaboration Manager or Philips Clinical Scientist) to understand whether their DICOMs are impoverish or whether desired details are stored in private tags the community does not know about. If the latter, open a dcm2niix issue to improve our converter.
