Oh, you're using a task regressor? That will not be convolved with the
HRF (or its derivative). The HRF/deriv only applies to paradigm files.
If you want that in your task regressor, you will have to do it yourself.

Yes, I think so. That would mean, that the additional frames correspond to the
weights of the derivatives, right?
But as I mentioned in the previous mail, they do have the same dimensions (in
matlab, checking the beta.vol).
Do you have any idea, wh
The -spmhrf 1 and 2 should have had additional frame in the beta.nii.gz.
Is that what you are looking at?

Okay, thanks.
But how can I find out the influence of the derivatives used?
I also tried to check the beta.nii.gz files for three different versions of the
analysis (-spmhrf 0 1 and 2), assuming that the weights for the derivatives
might be saved as
It uses the default parameters:
tau1 = 1;
tau2 = 1;
ttp1 = 5*tau1; % 6 %
ttp2 = 15*tau1; % 16 %
c = 1/6;

Hi Doug,
Thanks for your hint where to find the actual function.
But how can I find which values were used in my analysis? I.e. the input to
this function?
Best,
Laura
