your 2nd column is all 0s, which probably means you are missing one of
the diagnosis-gender combinations

Hi all,
I have reconstructed 12 paediatric subjects aged 4-13 and managed
to load qdec as well as generating stats. The factors are age,
diagnosis, gender and a continuos factor such as lh temporalpole
thickness. When i click analyze, the return is a list of errors as
follow.

What do i need to do from here?
Do i have to write a fsgd file/contrast etc? Any suggestions will be
most appreciated!
If i wish to use freesurfer for a paediatric group less than 10 years
old, what errors or difficulties should i be anticipating?
Thanks! Toh Wong
