Hello,
I have been trying to set up a flexible factorial design and when I try to enter my n-scan x 4 matrix with my factors I get an error saying the matrix must consist of natural numbers. 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?
Thanks!
