Dear SPMers,
Sorry for posting my question again, but I really need help using the Toolbox ArtRepair.
How do I generally detect artifacts with art_movie in the Contrast mode? How can they look like?
Watching the preprocessed data in "High Contrast", I don't really know what the different colours mean (-40 is blue, +40 yellow).
I tried the art_global function on a very noisy set of data and compared the results with art_movie. The repaired data looks much less red and yellow and there are more blue spots. Is this a good sign?
Thank you very much!
Best regards
