HCs always have 0 medicationload so it is not possible to measure a load
slope for them. Is it the case that a BD with load=0 is the same as HC?
If so, then just have one class. If not, do you expect the age, edu, and
tiv slopes to differ between the groups? If not, then use DOSS (default

Dear experts,
I would like to run mri_glmfit in a group analysis. However, I met the
following error when I added the medicationload as variable in my fsgd file.
Since I have 305 subjects and only 75 of these have medication load, it seems

smoothing). See the group analysis tutorial.

mri_glmfit command.

current folder. Also make sure it is readable by you

Dear Freesurfer Experts,
I was running qdec, and encountered an error while I was running the analyze
button on the qdec. Subsequently, if you can help with the following error
would greatly appreciate it.

It looks like your fsgd file may have been created on a windows
computer. Is that possible? Try reformatting it in linux or mac.

One thing you can try is to run this:

So, did it generate the error when you loaded the table or when you hit
analyze? List the steps and buttons that produce this error.

Hi Doug et al,
I'm trying to run an analysis in QDEC and continue to get an error that says
that the QDEC GLM design creates 0 factors.
I'm attaching my data table here as well as the output of QDEC. I've tried
deleting all variables in my data file other than one and testing just that
