Hi,
i am using afni version=AFNI_18.1.26 and while running my script, I get the following Warning after 3dToutcount:

What does this Warning mean? Is this a problem for my analysis and do I have to check on something?

Thanks a lot in advance for any help!

Hi Carolin,

This occasionally pops up with all-zero data. Is your data
already masked? Try adding a corresponding -mask option.

Thanks,
