Dear Sarah,
Validation of inputs in SPM12 are a bit more precise compared to SPM8.
Could you give an example of the factor matrix you are specifying? Does
it contain 0s?
Best regards,
Guillaume.

I've tried entering the matrix multiple ways and converting the numbers to int8 and uint8 and the matrix still wouldn't load. I've designed a similar model in SPM8 without any problems, but this problem started when I switched to SPM12. Has anyone encountered this problem or know how to fix it?
