Hello Rick,
In fact, I used the command exactly as Gang and you described it, but the first contrast is recognized as '+pleasant[0]' only.
Here is the entire gltsym section:
-num_glt 6\
-gltsym 'SYM: +pleasant[0] -neutral[0]'\
-glt_label 1 'pleasant_vs_neutral\
-gltsym 'SYM: +pleasant[0] -unpleasant[0]'\
-glt_label 2 'pleasant_vs_unpleasant'\
-gltsym 'SYM: +neutral[0] -unpleasant[0]'\
-glt_label 3 'neutral_vs_unpleasant'\
-gltsym 'SYM: +pleasant[1] -neutral[1]'\
-glt_label 4 'pleasant_vs_neutral_modulation\
-gltsym 'SYM: +pleasant[1] -unpleasant[1]'\
-glt_label 5 'pleasant_vs_unpleasant_modulation'\
-gltsym 'SYM: +neutral[1] -unpleasant[1]'\
-glt_label 6 'neutral_vs_unpleasant_modulation'\
The error message is still:
++ '-stim_times_AM2 1 onsettimes_pleasant_S1.txt' has 1 auxiliary values per time point
++ '-stim_times_AM2 1 onsettimes_pleasant_S1.txt' will have 2 regressors
