Hello,thanks for your reply.I have a question about taste fmri regression analysis.I have given the five taste stimulus,bitter,salty,sour ,sweet and umami. The fmri design is event design.different taste has different stimulus time.I run the 3dDeconvolve using the SPMG1 function for individual analysis.But it is strange that
the Bitter Resp Tstat and the Salty Resp Tstat have the same peak value location. The script as shown in the bellow:
3dDeconvolve -input pb02.$subj.r*.scale+orig.HEAD \
-censor motion_${subj}_censor.1D \
-polort 4 \
-num_stimts 11 \
-stim_times 1 stimuli/BitterResp.txt 'SPMG1' \
-stim_label 1 BitterResp \
-stim_times 2 stimuli/SaltyResp.txt 'SPMG1' \
-stim_label 2 SaltyResp \
-stim_times 3 stimuli/SourResp.txt 'SPMG1' \
-stim_label 3 SourResp \
-stim_times 4 stimuli/SweetResp.txt 'SPMG1' \
-stim_label 4 SweetResp \
-stim_times 5 stimuli/UmamiResp.txt 'SPMG1' \
-stim_label 5 UmamiResp \
-stim_file 7 motion_demean.1D'[0]' -stim_base 7 -stim_label 7 roll_01 \
-stim_file 8 motion_demean.1D'[1]' -stim_base 8 -stim_label 8 pitch_01 \
-stim_file 9 motion_demean.1D'[2]' -stim_base 9 -stim_label 9 yaw_01 \
-stim_file 10 motion_demean.1D'[3]' -stim_base 10 -stim_label 10 dS_01 \
-stim_file 11 motion_demean.1D'[4]' -stim_base 11 -stim_label 11 dL_01 \
-stim_file 6 motion_demean.1D'[5]' -stim_base 6 -stim_label 6 dP_01 \
