babs-init raises exception when there is no ses- folders in a non sub- folder.

[Michael-Sun]

When attempting to run babs-init, it determined that a folder in my BIDS directory 'code' was a subject and raised an exception:

Checking whether each input dataset is a zipped or unzipped dataset...
input dataset '1080_wasabi' is considered as an unzipped dataset.
Performing sanity check for any unzipped input dataset...

babs-init failed! Below is the error message:

Hi Michael! What's that code folder within your BIDS dataset used for? My understanding is that code should not be located within your BIDS dataset. Could you please remove this code folder?

@zhao-cy I think it's fairly common to have code directories in BIDS, along with other directories like source_data. We should have BABS only look for sub-* directories directly under the BIDS root

Ah sorry about this! Yes that's indeed a bug in BABS - thanks for letting us know, Michael! I'll fix it asap.

Note to myself: see function check_validity_unzipped_input_dataset() in utils.py. Seems this issue is only in validating the input datasets, but not when listing the subjects/sessions for analysis.

Hi @Michael-Sun, I just fixed the issue - could you please re-install BABS from GitHub main branch (instead of using pip install), and test it out on your dataset?
