Dear freesurfer-users,
I want to run a qdec analysis, comparing cortical thickness between two groups and using age and gender as nuisance factors. those factors are included in my data.table but when i want to chose the design i can only select gender as a discrete factor and not as a nuisance factor (see images attached). The second problem I have is, when displaying the results, I can't change the threshold. I can mark them but not change them. All the other buttons in the window work though. Thanks for your help in advance! Yours sincerely, Eva Wiedemann
PS: I'm using freesurfer v.5.3.0 on Ubuntu 15.10.

No images attached, but it is probably not an issue. When you include gender as a factor, the results will be controlled for gender, it does not matter whether it is listed as a nuisance variable or not.

This is a hard bug to track down as it is obviously working on other platforms. Zeke, have you seen this problem before?
Thanks for your help in advance! Yours sincerely, Eva Wiedemann
