All,

I'm just looking for a little advice on constructing fsgd and .mat files. I would like to compare a healthy control sample with the data from two MDD groups. To do so I made my fsgd file to look like the following:

GroupDescriptorFile 1 Title MoneyGame_Subjects Class Control Class MDD Class Anhedonic

Input REWARD111 Control Input REWARD201 Anhedonic Input REWARD207 MDD Input REWARD208 Anhedonic

Input REWARD211 MDD

Input REWARD212 MDD

Input REWARD213 Anhedonic

Input REWARD215 Anhedonic Input REWARD277 Control Input REWARD278 Control ....

This file results in a design matrix with 3 columns.

I am interested in conducting the following analyses and I wanted to check to see if I am coding all of the .mat files correctly.

Controls vs all Patients (1 -.5 -.5) Anhedonic vs MDD (0 1 -1) Controls vs Anhedonic (1 0 -1) Controls vs MDD (1 -1 0)

Thank you in advance for any help you can offer.

Avram
