Hi Danielle, that figure was created by using a Finite Impulse Response model (in SPM, but FSL can do FIR as well) and estimating betas at each TR. The betas were then converted to percent signal change. 

I haven't used it, but I think you should be able to use the fslmeants tool to extract the estimated timeseries for each of your conditions in order to perform a similar analysis.

Hi All,

I want to plot the average hemodynamic response across subjects for two conditions according to time (or the TR). From the research I have been doing, I haven't found something that does this easily in FSL. Is there a way to do this in FSL?

See below (figure a) for an example of what I want to do:

Thanks in advance,
