Running ANOVA

AFNI Message Board

Hello AFNI experts,

I am encountering challenges while attempting to run a one-way ANOVA. My goal is to examine the variations in brain maps across six different emotions.

I have collected data from each of the 10 participants, involving six runs. Each run was collected by presenting six emotional videos.

I would like to seek guidance using the example.

  1. Specifically, for the -dset, should I use the last processed block from all runs for all subjects? Or is there a need for organizing data to have only one specific factor?
  2. If I want to show the contrast between baseline and each emotion, do I need to average dsets for baseline, right?

Alternatively, could you provide any sample script for my specific case? It would be helpful to properly write down the input.

Thank you,
Jinsu

Jinsu,

I suggest employing 3dMVM for your analysis. Alternatively, you can use 3dANOVA2 -type 3 . Both of these options should suit your needs effectively.
