hello, afni experts.
I ran into a problem in GLT test, which is similiar to
[
afni.nimh.nih.gov]
Yet, unlike the "row" problem in the above post, I got error in numbers of "columns".
My maxlag is 6, so the matirx should be 4*7+2=30, yet the system said 1*12 is required. I am confused after several tries. Thank you for your help!
The details:
the command I used:
3dDeconvolve -input 043_038_017.1D -num_stimts 4 \
-stim_file 1 stimuli1.1D -stim_label 1 stim1 -stim_minlag 1 0 -stim_maxlag 1 6 \
-stim_file 2 stimuli2.1D -stim_label 2 stim2 -stim_minlag 1 0 -stim_maxlag 1 6 \
-stim_file 3 stimuli3.1D -stim_label 3 stim3 -stim_minlag 1 0 -stim_maxlag 1 6 \
-stim_file 4 stimuli4.1D -stim_label 4 stim4 -stim_minlag 1 0 -stim_maxlag 1 6 \
-glt 1 glta-c.mat -glt_label 1 "a-c" \
-iresp 1 s2all.irf -fitts runall.fit -fout -rout -tout -bucket s2all.bucket
ps: "a-c" means contrast of stim 1 vs stim 3
system reported error as following:
