External Email - Use Caution Hi!
I'm taking the liberty of writing another email on this subject, as I didn't get a reply to my previous email. My colleagues and I performed a general linear model with FreeSurfer mri_glmfit for whole brain analysis in intergroup comparison (g2v1) with a Monte-Carlo correction. I'd like to get the effect size of the analysis and I was wondering how could I get the eta squared or R2? I also saw that the gamma.mgh file was the contrast effect size. Could this be used as an effect size for this type of analysis? I believe an equation such as : pseudo_rsquared = (1 - model.llf / model.llnull) could be helpful but I wonder how to include this in the mri_glmfit script. Thank you in advance!
