Dear all,<br><br>I have a bit of an amateur question.  I&#39;ve read the slides and tutorial for group analysis, but I&#39;m still confused about the contrasts.  I made my fsgd file, which contains two groups: M and F.  I also have three continuous variables: Age, MMSE, Education.  I would like to test whether thickness is correlated with MMSE scores, after controlling for gender, age, and education.  What should my contrast file be in this case?  <br>

<br>Thanks for the help!<br><br>Cheers,<br>Linda<br><br>
