Hi,

I’m using the NBS toolbox to analyze differences between the results of two task conditions, in which I have two representative connectivity matrices for each subject. Regarding calculating the component size “intensity”, why does the NBS add up the t-values of each component minus the threshold value? I referred to the calculation of the variable test_stat_mat in the file NBS.stats.m. I would like to know the difference between this method and the calculation method that adds up the t-values of each component as they are, without subtracting the threshold. 

Thank you for your time. I look forward to hearing from you soon.

Best regards,

Makoto
