Hi,
as mentioned in the toolbox, TOM offers two approaches: one, in the
absence of a large group, TOM helps you by generating unbiased pediatric
reference data that is based on an external, large population. For that,
you need the TOM.mat that is available for download at the IRC site
(where you got the toolbox from in the first place). Two, if you have a
large population yourself, you can use TOM to statistically analyze your
own population (which then generates your own TOM.mat). With your group
size, you are a clear candidate for option one :)
Hope this helps,
Marko
