Hello Freesurfer community, I would like to extract individual brain activation values in specific clusters emerging from an FSFAST group analysis that tested a certain contrast during a task, to be entered as predictors in a linear regression model. Is it possible to obtain these individual level activation values using commands in FSFAST? Or is it possible to extract individual level effect sizes from this group analysis from the contrast effect size files? Thanks so much for your help! Angela
