Can a Mixed Model MANOVA Be Run from Long Form Dataset?

#1
Hello,

I'm hoping to run a mixed model MANOVA with 1 BSF (2 levels) and 1 WSF (3 time points). Right now, the whole database is set up in long format. Is it possible to run this analysis when the data is in long format? Or is it necessary that I convert it all to wide format?

Thank you for any help.
