Hi Doug, Martin, et al.,

I am going to use the LME tools for a study in kids 8-15 y.o. (some with brain injury). RE the target space (mris_preproc and mri_surf2surf), the LME wiki page says "study_average". I am unclear if this should be

a) average of all subjects at TP 1 (or final, or mid)

b) average of all subjects and all TP's

c) average of all within-subject templates (created from recon-all -base)

d) fsaverage

I suspect (d) is wrong for this study and (c) is right, but want to double-check. In that case, would I then follow the steps on the wiki page for creating a template?

Thanks,

Chris
