Hi!

I have an OSGM from a fixed effects group analysis with mri_glmfit. I would like to calculate the effect size and the 95% confidence intervals. I see from various threads on the mailing list that Cohen's d can easily be obtained from the outputs of mri_glmfit by dividing gamma by rstd.

I am wondering now how to compute the 95% CIs for Cohen's d from the outputs of mri_glmfit? 

Thank you very much!
