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.
