Hello,

i wanted to create a VBM with CAT12, ofc with MAtLab and SPM12, but there seems to be a mistake somewhere. Whenever i try to check homogenity (alone or inside of the basic model) the following error shows up:

The following modules did not run:

Failed: Basic models

I neither know what is meant with offset nor what i can change to repair CAT12. I already tried updating, but it is the newest version.

This also leads to no boxplot or other graphs being created. I just get an error screen and get asked if i wanna still save the data.

If anybody has an idea, i would be extremely grateful.

Hi Jack, 

no specific idea why CAT12 does not work, maybe some technical incompatibility with your very recent Matlab version?

Generally, I would suggest to send your request to the SPM mailing list, Christian Gaser is usually responding very quickly: https://www.fil.ion.ucl.ac.uk/spm/suppor...

Best wishes,

Marcel

Have you realigned the images before?
