Hi Diederick, the Smode is a measure of response strength or magnitude. Effectively, you can think of it to scale the time course. For a Smode of zero the IC is essentially absent for a given subject in the set. The more robust and consistent a component is for a set of sessions / subjects, the more clearly it deviates from zero and the smaller its variance will display (see the boxplots). Therefore, it is always a good idea to look at these boxplots (and the values). You can flip the sign by either flipping the Tmode or Bmode. Does that makes sense?

Could you verbally describe the meaning of this number in more exact terms? Thanks! Diederick On 23 mrt 2011, at 16:50, Andreas Bartsch wrote: Hi, the Smode is a good start to look at.

Besides presenting stat maps for each network, I would also like to have a scatter plot showing network strength against a behavioural measure, I looked into the stage 2 maps but am not sure yet how best to proceed. Any thoughts on a good measure to use for this? Many thanks, Diederick
