Thanks Doug! I'll try that instead.
Also, do you or anyone else happen to have the answers to my other questions (reposted below):
- When viewing the results in tksurfer, which color represents "left
hemisphere is larger" and which represents "right hemisphere is larger"?
If you are just doing a simple interhemispheric difference, then yellow/red will be left>right and blue left<right
- I have no idea how to view the results in tksurfer AFTER performing
the step of correcting for multiple comparisons. Any suggestions?
If you run mri_glmfit-sim with --help you will see a list of output files with descriptions for each. Choose the one you want and run tksurfer on it (eg, tksurfer fsaverage_sym lh inflated -aparc -overlay csdbase.sig.cluster.mgh )

Thanks! Krista

Run mris_preproc with --paired-diff-norm which will then compute LI = (L-R)/(.5*(L+R)) Note that some people use LI = (L-R)/(L+R) If that is what you want, then divide the mris_preproc result by 2 doug On 12/08/2013 08:45 PM, krista kelly wrote: > Hello, > > I'm analysing interhemispheric differences using xhemi.
