Hi-

A couple comments, but these won't really be solutions, likely, just features:

1) You have two backslashes, separated by a space, in a row at the end of your first line: "\ \"
I just spaced the text out a bit here (without that double slash):

2) for choosing a duration modulation specification, these notes will likely be helpful:
https://afni.nimh.nih.gov/pub/dist/doc/htmldoc/statistics/deconvolve_block.html
We generally recommend using dmUBLOCK() with a negative argument, whose magnitude is the mean stim duration.

3) You might want to specify the number of GLTs explicitly:

-num_glt         2

4) Your current GLTs are just sign-flips of each other. You shouldn't need to do that---we do 2sided testing by default, unlike in some other software. The importance and relevance of 2-sided testing in most MRI analyses is described here:
Chen G, Cox RW, Glen DR, Rajendra JK, Reynolds RC, Taylor PA (2019). A tail of two sides: Artificially doubled false positive rates in neuroimaging due to the sidedness choice with t-tests. Human Brain Mapping 40:1037-1043.

5) I don't see any motion regressors there in the model?
