Hi,

i am new to afni and i am currently trying to learn how to use this program. For practice I would like to use uber_subject.py to generate a script. I encountered the following problem: in the section 'symbolic GLTs', I use the 'init with examples' button to give me some suggestions for contrasts.
When i click later on 'generate script' i get the following error message:

GLTsymtest errors
valid GLT labels are: 'vis aud'
**GLT ERROR for gltsym 1: 'vis -aud'
**GLT ERROR for -gltsym 2: '0.5*vis +0.5*aud'

The first label is 'V-A' and the symbolic GLT is 'vis -aud'
The second label is 'mean.VA' and the symbolic GLT '0.5*vis +0.5*aud'

I don t understand what i am doing wrong, especially when those contrasts were generated by using the 'init with examples' button.
It would be great to get some help on this!

Thanks a lot
Carolin
