Hello all, I am running a gyrification analysis between 3 groups. So I modeled my GLM like the one on this page: https://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf3G0V <https://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf3G0V>
I was wondering if it is correct to run a Monte-Carlo correction on the results of the Main effect of group (contrast 4 on the page), which represents an F test if I am correct. I use the line mri_glmfit-sim --glmdir Results.rh.00.Groupeffectseul --cache 2 abs --cwp 0.05 --2spaces I get no sig Monte-Carlo corrected results on the main effect of group whereas I find interesting sig results in the one-by-one contrast, which is a bit surprising. Thank you for your answer. ——— lnc-autisme.umontreal.ca En apprendre plus sur l’autisme: http://grouperechercheautismemontreal.ca/Magazine.aspx <http://grouperechercheautismemontreal.ca/Magazine.aspx>
