Matlab creates a mask to limit GLM analysis to in-brain voxels. This is calculated based on a intensity threshold, perhaps it is too stringent. Look at your Mask.img file in the glm output folder and make sure ~isempty(mask).

Hi Erica,
thank you for your reply! Actually, I am not using a mask. That's why I was so puzzled by this error message.
Best,

Are you using masking? I've gotten this error before when I created a binary mask incorrectly (the mask was just black, so of course there was no area for the program to analyse data within). Hope this helps!
