Questions about effice size cohen's f2

Submitted by jujube on

Dear Dpabi experts
 I conducted a paried t-test on RS-fMRI metrics, I got TP.nii and TP_cohen's f2.nii. I am confused about why the effect size map for paired t-test was calculated in the form of cohen‘s f 2 instead of cohen‘s d.
I appreciate your clarification, thanks in advance for your time and reply.

Hi Ei,

As far as I can see, there is no particular reason for this. 

I suggest you to transfer cohen's f2 to cohen's d if you prefer the latter one.
