There is still no difference between that and doing a regular thickness study with two groups. Were are you getting stuck? doug On 01/17/2014 12:35 PM, krista kelly wrote: > Hi Doug, > > Sorry I should have specified BETWEEN groups analyses. I have two > groups (control, patient) and I wanted

Hi Doug, Sorry I should have specified BETWEEN groups analyses. I have two groups (control, patient) and I wanted to see if the hemisphere asymmetries (or laterality indices) differed between groups. Is there a way to do that? Thanks for all you help! Krista On Mon, Jan 13, 2014 at 6:25 PM, Dou

yes, it is just like a "normal" group analysis. You create a stack of LI maps, one for each subject, create an FSGD file, run mri_glmfit, then mri_glmfit-sim. doug On 01/13/2014 06:22 PM, krista kelly wrote: > > Just wanted to repost this in case anyone else can give some advice. > Thanks!

[Freesurfer] Fwd: xhemi correct for multiple comparisons

Just wanted to repost this in case anyone else can give some advice. Thanks! Is there any way to analyze group differences with xhemi? I can get the laterality indices per group, but I'd like to do a whole brain analyses looking at group differences in laterality indices. Thanks, Krista On Tue,
