Hi AFNI users,
I have a question regarding proc.py gltsym. Below is the part of the proc.py script I am using which I intended to subtract brain activation during NF from F (F-NF).
-regress_stim_labels F NF \
-regress_basis 'BLOCK(4,1)' \
-regress_censor_motion 0.3 \
-regress_opts_3dD \
-gltsym 'SYM: +F -NF' \
-glt_label 1 F_vs_NF \
If I'd like to do the subtraction on the other way around which is subtracting brain activation from F from NF (NF-F), can I simply change the gltsym into 'SYM +NF -F' and glt_label into NF_vsF?
Thanks for reading this question,
Jun
