Hi all,

I think the degrees of freedom in my analysis has an error. I've searched the forum but can't seem to find a description of how the degrees of freedom are calculated within the results explorer of ROI to ROI analyses.

For some background: I have 31 subjects in this analysis and included 3 variables within the subjects effects-- all subjects, age, and my main variable of interest, which is a continuous variable. I specified the between-subject contrast as [0 0 1]. I am investigating the connectivity of one seed ROI with 20 other target ROIs.

However, the degrees of freedom for the F test within the results explorer for the connectivity to the seed ROI are F(7)(22). The t-stat correctly displays T(28) degrees of freedom.

Can anyone offer any insight? I appreciate the help.
