I’m working on scripts for analyzing BIDS-formatted fMRI data. I would like to keep the outputs consistent with upcoming BIDS releases (incorporating derivatives extensions), and am trying to figure out which metadata fields I should specify relating to spaces/atlases.
Based on my understanding from documentation online, BIDS 1.4.0 has a SpatialReference field, specifying an atlas or reference image. The working copy of the BEP014 suggests that this information will be in two fields, ReferenceMap and NonstandardReference, depending on whether the reference is standard.
A few questions, for @oesteban or whoever is aware -
Will ReferenceMap and NonstandardReference supersede SpatialReference, or will the latter still be used for anything?
I frequently analyze data in a functional template space defined per individual subject - i.e., one functional image that all runs/tasks for a given participant are registered to. Has there been any consideration of adding dedicated “space” labels for such functional template spaces, along the lines of the “individual” or “fsnative” labels for individual anatomical spaces?
