A couple of points - too long for a comment: If you are protecting your pre-planned tests with Bonferroni correction, than there is no need to run the original ANOVA. The "double protection" only looses power. Most of the standard "post-hoc" tests for ANOVA do not need the protection of the original F-test.

The Greenhouse–Geisser correction is a statistical method of adjusting for lack of sphericity in a repeated measures ANOVA. The correction functions as both an estimate of epsilon (sphericity) and a correction for lack of sphericity. The correction was proposed by Samuel Greenhouse and Seymour Geisser in 1959. The Greenhouse–Geisser correction is an estimate of sphericity (). If sphericity is met, then . If s…
