Heudiconv - AttributeError: 'tuple' object has no attribute 'dim1'

Dear all,
I run the docker, an example from a control group (CTRL):

docker run --rm -it -v /Users/bids:/base nipy/heudiconv:latest -d /base/Dicom/CTRL{subject}//MR. -o /base/Nifti/ -f /base/Nifti/code/heuristic.py -s 31 -c dcm2niix -b --overwrite --minmeta

Ahoi hoi @Tali_Weiss,

your post appears to be cut off/missing some parts, but based on what’s there,
I assume you’re asking why your conversion is failing with that error, eh?

Based on the heuristic you shared, you might want to change for s in enumerate(seqinfo): to the line above you commented out: for idx, s in enumerate(seqinfo):, because enumerate returns a tuple of index and value. As you want to access the information in value you need to adapt your code to for idx, s as otherwise you end up doing the following (idx, value).dim1 and thus your error.

HTH and if not, let me know and I’ll try to explain it better.

Cheers, Peer

Thank you! It works when I change it to idx, s in enumerate(seqinfo):
