fMRIPrep and PyMVPA naming discrepancies & .bidsignore ignored

, ,
1

fMRIPrep names bold files thus:
sub-02_task-ao_run-01_space-MNI152NLin2009cAsym_desc-preproc_bold.nii.gz
while PyMVPA would like them to be named thus;
sub-02_task-ao_run-01_space-MNI152NLin2009cAsym_preproc.nii.gz

PyMVPA seems to ignore my .bidsignore file as well.

Would appreciate your advice on how to handle this.

Thanks,
John

I am not sure what is the problem here, but let me provide some information that might help:

  1. The Derivatives extension to BIDS has not been finalized and over time went through evolution. Different software packages have kept up with that evolution to different extent - this might explain the discrepancy. To track progress on finalizing the Derivatives extension please go to: https://github.com/bids-standard/bids-specification/pull/109

  2. bids-validator has not been yet updated to understand and validated derived datasets

  3. .bidsignore is not part of the BIDS standard (at least not yet) and it’s just a configuration file internally used by bids-validator.

I hope this helps!

Thanks. I forgot /derivatives was still the Wild West.
