It sounds like waver "data when" will work for me.
In the FSL study design and output it graphs for you the time series of the data times that you put into it. It'd be great if afni could read that or read the same text file and convert it into a graph that appears below the afni graph so you could see if the activity correlates with your timings (especially in event related studies with random event times like mine). To put it into waver I have to rearrange the txt file a bit.
thanks very much.
