This is not possible with QDEC, but you can use an FSGD file to do it (or set up your own design matrix). Do a search on our wiki for FSGD to see examples.

Hello,

I would like to be able to do 3-way anova in qdec, freesurfer version 4.3.1 and measure the cortical thickness and volume. Is this possible? I have 3 discrete factors, each with two levels:

age group: less/more than 50 HIV: yes/no Alzheimers: yes/no

When I try to click on the third discrete factor in the qdec design tab, it deselects one of the others. Does it max out at two?

Thank you very much, Jeff Sadino
