Dear AFNI experts,

I ran 3dMVM for resting-state data and got some brain regions that survived the statistical threshold. I then ran 3dmaskave to extract z scores from each surviving region, but for some reason, almost all subjects' z scores appear zero, although it seems there were no problems during extracting the data. I have attached the screenshot of the terminal and extracted values. I did exactly the same for another analysis which resulted in non-zero values. Could you please let me know what could be an issue here?

Best,
JW
