I must have misunderstood the previous emails then. I though you suggested smoothing the anatomical data prior to registration to avoid the noisy numbers. Glad that is now cleared up, thank you.
Is there a way to find out how many vertices are on the fsaverage_sym surface?

You should not smooth before registration. doug On 07/16/2013 10:20 AM, Boratyn, Daria A. wrote: > Couple of quick things in regards to smoothing prior to calculating > the LI.
