Hi,
I'm using dcm2niix v1.0.20241211 to convert my DICOMs to BIDS format. The scanner is a Siemens MAGNETOM Skyra.
The data properly converts but the metadata in the .json file is much more bare than the .json I get if I just use dcm2niix directly on the DICOMS. Any reason as to why this might be?
Thanks in advance!
Kylie
I would recommend using the current stable release (v1.0.20250506)

I am unsure what the question is - it seems like you are
converting the images two different ways and getting diferent
JSONs, but I do not know what the difference between the "direct"
and "indirect" mode. I would convert the files like this:
dcm2niix /path/to/DICOMs
Is there some other tool you are using? If so does the tool use
the same version of dcm2niix (the JSON should report the version
`"ConversionSoftwareVersion": "v1.0.20250505"`).
dcm2niix should populate the fields of the DICOM, those these vary
from a system running V (e.g. VE11) versus XA (e.g. after
upgrade to XA30). Note that the CSA headers are crucial for
many sequence details, so enure that your PACS or anonymization
scripts do not remove these from the DICOMs before dcm2niix
converts them.
