thank you! Angela
You can use --paired-diff-norm instead of --paired-diff, this will compute
(L-R)/((L+R)/2)
You can then divide the output by 2, eg,
fscalc output.mgh div 2 -o output.div2.mgh

Hi all, I have a question about hemispheric asymmetry analyses. The example given in the wiki shows how to compare lh and rh using a paired t-test. Is it right? But how can I calculate (and then compare groups) the laterality index (L-R)/(L+R)? Thank you very much for any help
