[VoxBo] How to run a FIR analysis

[Dan Acheson]

I ran a study with a rapid event-related design using a random jitter of 
the trial length (minimum 2 TRs, max 12 TRs), intending to use a FIR 
analysis. I initially ran a FIR with 2 basis functions, but this 
produced nonsensical results, and there were estimates for each FIR 
basis function. Two questions: How do I run a FIR and is there a way of 
getting a single estimate for a given condition, rather than an estimate 
for each basis function specified?
