Hi everyone,

I want to analyze with DOSS the relationship between performance on a cognitive task (called '15wt') and cortical thickness, in one group, controlling for the effects for age, gender and education. As a Freesurfer-newbie, it be would really great if someone could check my .sfgd file and contrast.

.sfgd file:

GroupDescriptorFile 1

Class .00 plus blue (this is the gender part)

Class 1.00 plus red

Variables 15_wt Age Edu

Input 0050 .00 52 73 4

Input 0051 .00 38 68 5

Input 0054 1.00 35 57 4

Input 0060 1.00 46 58 6

Input 0062 1.00 46 45 5

etc.

contrast:

0 0 .5 0 0

Is this correct? Thanks in advance!

Anita
