If you run the cluster-based correction for multiple comparisons (mri_glmfit-sim), it will create a table of clusters with their areas and the average contrast in each cluster.

Hi,

I’m currently running analyses in Qdec and have identified areas that show significant effects in my contrasts. I have two questions related to interpreting these results.

1. How can you interpret the effect in each “blob?” (i.e., which group has a greater cortical surface area, etc.). Right now, all I know is that there is an effect in certain areas. Can you export this data to get means and standard errors?

2. Is there a way to localize where these effects are? E.g., a tool that tells you this effect is located in __ area of the brain?

Thanks in advance

Courtney
