Hey guys,
This is not really an issue, so I'm not sure if this is the best place to ask this... Should I post to the gablab list instead? the nipype mailing list?
I've never used rapid art as my artifact detection tool before and I was hoping to find more information than the following about how it works, including the math behind it and perhaps also a notion about what good thresholds to use are (especially in different populations).

Thanks! Sorry if this is the wrong place for this question!!

You want the analysis-MIT list. :)

(sent from phone; probably more terse than usual)

@amyfinn, @toddt : i think this is ok as well. (i kind of prefer it, because its easier to search and follow discussions, but not everybody is on it - should we get everybody on it?) that said, things like this should go on to the wiki and become faqs.

amy: the page you were looking at is ancient - did google bring that up? here is the current page for the released version

http://nipy.sourceforge.net/nipype/interfaces/generated/nipype.algorithms.rapidart.html

the general idea is that a zthreshold of 2-3 and a composite motion norm of 0.5-1 is good for adults. if you are looking at kids, then you may want to increase the motion threshold.

Helpful! Thanks guys!
