Hi Doug,
is there a way to perform asymmetry analyses for local gyrification index?
In my xhemi folders there is no LGI surface.
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
You can copy the rh gyrification index to xhemi/surf/lh gyrification
index, ie, copy it to xhemi/surf, but change the name so that it appears
to be lh instead of rh

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
