Dear Alfonso,

Hope you're well! I've been trying to figure out why I am having an error message pop up when trying to add new ROIs to an analysis. It's the old "matrix dimensions must agree" error haha (pasted below). I double checked things and for sure the x,y,z are the same as the other ROIs, and as the images, and all are normalized in MNI space. The error message seems to pop up for Subject 5. Subject 5 isn't in the group analysis I'm trying to do, so I tried skipping that subject when adding the ROIs to the first level (everything goes well during Setup and Denoising when adding them), but during second level I get an error message that data are missing for Pre.(It's a Pre-Post design). I tried updating to both versions 17f (the one right after the one I'm using, which is 16b) and to the latest version of 20, but 17f logs me out when I load the .mat file, and 20 gives me an error message when starting.

Thanks for any help : )
Mary
