I am hoping to start some group analysis and I have downloaded the AFNI Matlab Library from this website: https://sscc.nimh.nih.gov/afni/matlab/
I just want to confirm that this is the latest library I should be downloading for analysis.
Than you in advance for your help.
We don’t support or maintain the Matlab libraries anymore, and those are likely quite old.
What kind of group analysis are you interested in performing?
I was hoping to run a 4-way ANOVA:
Group (2) x Phase (2) x Reinforcement (2) x Subject (38)
Tamara, that can be easily done with 3dMVM. Or, you can even use 3dttest++ / 3dMEMA if you are willing to tease apart the ANOVA structure into multiple individual t-tests.
Thank you Gang for the suggestion. I am just looking into 3dMVM right now for the first time and I am going through the examples. If is still suggested that I include subject as a random effects if I use 3dMVM?

No, you only need to specify those between- and/or within-subject factors plus quantitative variables (if applicable) in 3dMVM.
