Second pass error : KeyError: 'ScanningSequence' #114
Comments
Updated the format of protocol_translator |
I have narrowed the problem down to the sequence "ep2d_diff_mddw_30_p2 A>>P iso2.0 b1000+2000_ColFA" not containing "ScanningSequence" in bids_purpose. I am not sure why would that not contain that key and also don't know what would be the work around. Any suggestion would help. Thanks. |
Sorry for the slow response and this might be too late to be useful.Probably the first thing to do is check whether ScanningSequence is present in the JSON sidecar for this series in your work directory where dcm2niix outputs converted data. If this particular field is absent from the JSON sidecar, check whether the original DICOM files for this series (in sourcedata) have the (0018,0020) ScanningSequence tag present. dcm2niix should fill this JSON field regardless of modality (https://github.com/rordenlab/dcm2niix/blob/master/BIDS/README.md). As a side note, the ">>" or "+" may cause issues for dcm2niix, but I haven't tested that hypothesis. |
Hi,
I have been using bidskit to process scans for last couple of months. I have older version of bidskit that works as intended so I tried using the latest BIDSKIT 2022.10.13 with dcm2niix v1.0.20220720. I am getting the following error on my second pass;

This is what my Protocol_Translator looks like;
