Hello Gang,

I tried to run the deconvolution script I prepared (see below), but I keep having problems calculating the contrasts. If I have spaces in the gltsym lines, it won"t do the contrasts at all, if I take out the spaces, it calculates nonsense and gives the following message:

++ '-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

Can you see what the problem is? The experiment consists of the presentation of pictures of different valence (pleasant, neutral, unpleasant, filler items [others]) for 18 sec. The corresponding valence ratings the participants gave for these pictures (except for others) were used as modulation parameters.

It would be great if you could help me with this problem.

All the best,
Jana
