Dear FreeSurfers, I hope you can help me out with a problem in coding my fsgd file. I want to examine the difference between two cognitive measures on cortical thickness in one group. Furthermore, I will correct for age (centered covariate). So, I have 4 variables: group (class), 2 cognitive scores (continuous) and age (continuous). How can I compare two continuous variables? I have tried to list them as two variables in the fsgd (so not class): e.g: Input101 group 2.3 1.9 -0.5 (number of subject / group / score 1/ score 2/ age) Then I ran the dods model with the contrast 0 -1 1 0, which ended up with a surface sig file. However, when I look at the scatterplot in tksurfer, I cannot see the two cognitive variables at the same time. Is there a better way to do this?
Thanks a zillion times :) Best wishes Heidi ================================================ Dr. Heidi Jacobs Postdoc researcher Faculty of Health, Medicine and Life Sciences School for Mental Health and Neurosciences Division Cognitive Neuropsychiatry and Clinical Neurosciences Alzheimer Center Limburg h.jac...@maastrichtuniversity.nl www.maastrichtuniversity.nl www.heidijacobs.nl Dr. Tanslaan 12, 6229 ET Maastricht P.O.
