Dear sir, madam,

 

I am currently using Freesurfers Qdec and I have a question about the statistical output: is it possible to have a peak p-value that is larger (i.e. less significant) than the clusterwise p-value?

My peak p-value (after using a - log10 transformation) = 0.0038, while my clusterwise p-value = 0.0029.

 

Could you maybe give an explanation how the clusterwise p-value is computed?

 

Thank you very much!

Kind regards,

Las Blawimo
