Hello everybody,
I am trying to run 3dDeconvolve in an experiment with volumes being acquired at irregular times. I'm designing the experiment right now and I want to use 3dDeconvolve -nodata to search for a statistically efficient design. However, based on the documentation I only see how to specify regularly spaced scan times (e.g. with the option [-nodata [NT [TR]]).
In the design that I want to run, I have for every trial ~3s of silent time (no scanning because I present sounds to participants) and then I acquire say 2 volumes in 2s each. That means that the scans occur at irregular times, e.g. at times t=[3,5,10,12,17,18,...].
Can anybody help me with how I should enter this design into 3dDeconvolve? Much appreciated.
Floris
