Hi all,
We strongly recommend using direct paths to access the data in the code execution environment rather than using glob() . First import /code_execution/data/submission_format.csv , and then use the UIDs in the submission format to build paths to the nifti images: /code_execution/data/niftis/{uid_from_submission_format_row}.nii.gz . Often it takes ~15-20 seconds for the data to mount and allow listing or glob, but direct path access (as demonstrated in the examples in our runtime repo) should work immediately. Please let us know if you have any questions, and thanks!
