Just thought I would add to the previous message that I am using SPM5
Hi all,
I'm venturing into the unknown and trying to set-up a event-related design with the FIR basis function in order to get a condition by scan interaction.
I have 3 conditions and I have a TR = 1.5 and the duration of each trial is 18s, so 12 scans). So I set up the model with 2 factors (scan and condition) and changed the basis function to window length = 1.5 and order = 12 (since there are 12 scans). I then ran the model and got this error message
Error running job:
Assignment has fewer non-singleton rhs dimensions than non-singleton dimensions subscripts.
I'm not sure what this means and what I have done wrong.
Can anyone help?
Thanks
Nick
