Hi,
It’s a standard Cohen’s d calculation -- mean of the individual subject (lev2)
copes, divided by the std of the individual subject copes
In terms of FSL code, if $mergedcope is the 4D file containing all the
individual subject cope estimates, the code is just:
fslmaths $mergedcope -Tmean ${mergedcope}_mean
fslmaths $mergedcope -Tstd -div ${mergedcope}_mean -recip cohensd
cheers,
-MH

Subject: [HCP-Users] How does the HCP calculate the Cohen d effect in S1200
GroupAvg results?
Dear HCP users
I've downloaded the S1200 GroupAvg results from the HCP website, and looked up
the 7-task Cohen d effect results.
Could anyone tell me how the Cohen d effect was calculated?
Was it calculated by Cohen t-test d effect size of the beta value of GLM to
each task?
Thanks, ~^_^~
