I have used gltsym before for contrasts but for reasons I don't understand (I thought it was a white space error or something) when it plug it into the afni proc the gltsym in the tcsh is all over the place for example ' separating parts of my titles. I ended up fixing the gltsym part of 3dDeconvolve on my own but I get command not found errors for gltsym. Below is an example of what I put into the afni proc. Note: I have changed labels and paths in order to save space. If you want the original text I can send it to you via email.

Thanks for your help
