Hi experts,
I'm trying to process my macaque data with afni_proc.py. I followed the example scripts from @Install_MACAQUE_DEMO_REST.
An error that reads "** FATAL ERROR: -polort value can't be over 20" occurred when running @radial_correlate( see the attachment). I tried to add a flag "-radial_correlate_opts -polort 18 ", but changed nothing.
Could you please tell me what should I do then?
Best,
Jewel
