RE: v15 ART scrubbing
I never thought of editing the .m
file. I've been trying to figure out how to get Conn to command ART
to also save a copy of the graph .jpgs. Maybe this is how...
If you run ART on it's own via MATLAB (command: art) though, the default z-threshold is indeed 9, and translational movement threshold is 2mm. Something I just figured out is that if you run ART-based Scrubbing via the PreProcessing GUI it will save motion outliers using 'comp motion' (composite?), whereas if you run the toolbox on its own you have control over checking off the last box to also include rotational movement in your regressor files. The latter reveals a lot more outliers than the 'comp' default option but it is not automatized via the Conn GUI.
Anyway, maybe there's a patch for v.15 that will come out soon to be able to change the thresholds (maybe hopefully rotational thresholds, too) before the Art-based Scrubbing begins....

Just to bump up this conversation - I believe
the default in ART/Conn should be z = 3 for outlier removal, but it
remains 9, even after I edit the art.m file in the conn
folder. How might I proceed?
