Hi, I have gotten the lh and rh ROIs stats with mris_anatomical_stats before, is there any statistical tests in particular that you recommend for asymmetry? What I have done is a two-way anova and paired t-test with Bonferroni correction. Would like to hear your opinion on that.
Also, I would be interested in the vertex-wise analysis, I will look into that. How can I do the xhemi analysis after make_folding_atlas? Thank you!
