Reading through the fine SPM manual by Dick Veltman and Chloe Hutton I
came across the following in the section on event related fMRI model
specification"
basis functions (Finite Impulse Response): uses a set of 'mini-boxcars'
to model peri-stimulus time.
In my version of spm99, this option is not available. If I search
through the code of spm_get_bf, I don't see this. It also doesn't seem
to be in the updates.
This is a great way to do the analysis. I've been doing it by hand and
it's a pain.
Any info would be greatly appreciated.
Thanks,
Souheil
