Hi Doug,
Thank you for prompt reply. So I should remove '-gammafit', and add '-fir 4 24' is for mkanalysis-sess.new?

If you want a time course, you should use an FIR model, something like "-fir 4 24" to start the time window 4 sec before the stimulus onset and stop it 20 sec after stimulus onset. Do not include -gammafit.

Hi all,
I want to plot the hemodynamic response of a voxel after my analysis finishes. I hope I can get the hemodynamic response of each voxel for each session, so I can see the statistics by myself.
My analysis.cfg is below:
-gammafit 0 8 -gammaexp 0.3 -timewindow 40.0000 -prestim 0 -polyfit 2 -TER 2.0000 -autowhiten 40 -nskip 0 -fwhm 0 -extreg mcextreg -nextreg 3 -rescale 1000
After I ran selxavg-sess, I got the following volumes: h0.nii, h0-offset.nii, h.nii, h-offset.nii, rstd.nii, rvar.nii. How can I get a response from these volumes?
