Hi,
This is an incredibly basic query but I thought it would be faster to just ask!...
I have 2 runs which I concatenate together, and I usually specify in 3dDeconvolve where in the concatenated file the second run starts with the -concat option.
I have just started using the amplitude-modulated regression option in 3dDeconvolve however, so rather than first creating my regressors with waver (which I am more used to doing) I am directly inputting the stim times, and I am unsure how I should represent the 2 runs. Should I literally just cat the 2 stim files together (run1 and run2 tagged on at the bottom) and then use the -concat option?
This is what I first tried but have been getting errors about "near duplicate times" when I run 3dDeconvolve so clearly this is not working!
Any help with this matter would be greatly appreciated,
Liz
