Dear Freesurfer experts,

I am attempting to estimate the Cohen's D effect size of significant clusters using the suggested command:

fscalc gamma.mgh div rstd.mgh -o cohensd.mgh

Now, I get the cohensd.mgh file but I am not able to open this file. How can I see the particular effect size of each significant cluster included in the sig.cluster.summary file?.

Thank you very much for your help!

Best regards,
