Replicable scripts, BIDS, and curating data

Is this something that has been implemented/could be accessed when running fMRIPREP? For example, I have some subjects who have two T1’s, and one of them has much more motion distortion than another, so I’d like to have FMRIPREP only use the good T1 rather than averaging them together. How could I point fMRIPREP to that column in order to decide which T1 to use?

This would be an interesting new feature. However, FMRIPREP currently does a robust averaging of T1w images that excludes outlier voxels. Check if the output volume looks good. Perhaps manual exclusion is not necessary.

I know I could just put a number of specific subject file names into the .bidsignore file, but that doesn’t seem to be the best long-term solution.

I agree (and I’m not sure if FMRIPREP uses .bidsignore anyway). A solution based on a specific column in _scans.tsv would probably be best.
