Hi, I'm trying to run tICA on a block design (30s ON 30s OFF). The design is the same for all sessions/subjects, however, due to the instrumentation we are using, which is not quite up to snuff yet, there is a little bit of random variance in their onset/offset across sessions/subjects (I'm guessing the range is at most 1-2s; with my TR being 700ms). I know the recommendation is to only use tICA when the timeseries/events are the same across sessions/subjects, is this degree of jitter (in some participants) enough to kill the whole point of doing a tICA? (I realize it will, to the very least, affect the participants for whom there was more jitter) Cheers Martin ######################################################################## To unsubscribe from the FSL list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=FSL&A=1
