Hi All,

Apologies in advance for the simple question:

Sometimes I am able to see which voxels are masked (white background) and which voxels are not in my mask (gray background). I can't seem to figure out why sometimes it works and sometimes (now) I can not get the mask I have created to do this operation in the AFNI graph vieer. I created my mask in matlab, saved as nifti, and then re-saved as BRIK in AFNI. Any insight into how to toggle this function would be greatly appreciated.

Thank you!
