Hello,
I'm trying to use the gltsym command with 3dDeconvolve to run linear tests between my conditions in different time points.
I don't understand in the output matrix the order and the numbers of the lags. By defining the lags [2..4] I expected to get 3 time points for each variable, and not 4 (as the output suggests).

INPUT:
3dDeconvolve -input r4.$sub.pic.scale+orig.HEAD \ \
-mask $sub.struc_al_ss_mask+orig \
-censor $sub.pic.WholeBrainF.Censor.1D \
-num_stimts 6 \
-stim_times 1 ../O$ord.Vio.txt 'CSPLINzero(0,15,6)' \
-stim_label 1 violence \
-stim_times 2 ../O$ord.Dgt.txt 'CSPLINzero(0,15,6)' \
-stim_label 2 disgust \
-stim_times 3 ../O$ord.Ero.txt 'CSPLINzero(0,15,6)' \
-stim_label 3 erotica \
-stim_times 4 ../O$ord.Fam.txt 'CSPLINzero(0,15,6)' \
-stim_label 4 family \
-stim_times 5 ../O$ord.Obj.txt 'CSPLINzero(0,15,6)' \
-stim_label 5 object \
-stim_times 6 ../O$ord.Peo.txt 'CSPLINzero(0,15,6)' \
-stim_label 6 people \
-jobs 2 \
-gltsym 'SYM: +violence[2..4] -disgust[2..4]' \
-bucket $sub.stats.GLTtest

OUTPUT:
GLT matrix from 'SYM: +violence[2..4] -disgust[2..4]':
0 0 1 1 1 1 -1 -1 -1 -1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0


Any suggestion would be greatly appreciated.

thanks,
nicola
