Hello!

 

I am having trouble with creating my contrast files. I did go over FsfdExamples (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FsgdExamples). However, I am unsure how should I create my contrast files if I want do a 2 group comparison while controlling 4 covariates:

 

Class:

Patients, healthy control

 

variables are:

Age,gender,episodes,residuals,  

 

 

Here is how I set up my contrast files:

 

1 -1 0 0 0 0 0 0 0 0  - Contrast1 (measure group differences)

1 -1 0.125 0.125 0.125 0.125 0.125 0.125 0.125 0.125 – Contrast 2 (measure group differences while accounting for covariates)

 

 

 

For some reason I think I am setting up those contrast files wrong… Any help is appreciated.

 

Best,

Liliana
