External Email - Use Caution
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 additional dimensions, but the dimensions were the same for all (163842x1x1x10).
I feel like I am missing something here, or maybe there is some mistake in my analysis? This is what I used:
mkanalysis-sess -fsd bold -stc siemens -surface fsaverage lh -fwhm 5 -notask -spmhrf 0 -TR 2 -polyfit 2 -analysis Test0.lh -per-run -taskreg PupAvg 1
selxavg3-sess -s S05 -analysis Test0.lh
And Test1/2 with -spmhrf 1/2, respectively.
Thanks in Advance!
Laura

It uses the default parameters: tau1 = 1; tau2 = 1; ttp1 = 5*tau1; % 6 % ttp2 = 15*tau1; % 16 % c = 1/6;

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

External Email - Use CautionHi everyone,
I need some help regarding the SPM-HRF with two derivatives: Where can I find the actual function that was used for the analysis? I am mostly interested in the peak latency, but would also appreciate if I can check the other parameters of the function somewhere.
Best, Laura
