Re: [Freesurfer] Freesurfer@nmr.mgh.harvard.edu

Are those the qdec files that generate the first error? That error implies that fsaverage is included as a subject in the qdec file. Is this possible?

Dear Dr Greve,

Thanks for your reply. I have already linked fsaverage to my SUBJECTS_DIR but the error still persists.

Attached is my qdec (long and cross) files.

Thanks.

Regards, Heidi Foo

    Dear FreeSurfer experts,

    I am trying to compare between stable WMH group and rapid
    progressed WMH group in regards to the cortical thickness as
    well as volume changes in the gray matter. The nuisance
    variable in my case is age. I ran my analysis using QDEC but
    encountered a few problems:

    1. There is error in analyze: couldn't open file

It looks like it cannot find fsaverage. Link it to your
SUBJECTS_DIR if you have not already.

    2. If this error doesn't appear, another one does.
    QdecGlmDesign::Create: zero factors!
    (Attached the screenshot of the errors for your perusal)

please send the qdec file


    I am hoping that you could give me a solution to my problems.

    Thank you so much.

    Regards,
    Heidi
