That looks like the terminal output for qdec. You cannot use qdec with your design. If you have questions about the FSGD, I'll be happy to answer them.

Hi Doug,
Thank you for your response. I tried the link which you sent yesterday. But got stuck while creating qdec.fsgd file. Below i have pasted the terminal output after loading the data.

I highlighted the discrete factors in yellow color. I wanted to know how to go about this classes such as birthplace, living and upbringing place.
Also, let us know whether the below-pasted information is in the right format for qdec.fsgd file?? Here we have birth, living and upbringing places as main classes and statutory, census and rural as subclasses. So, my question is that the below-pasted classes are ok or not?? If not, just needed your assistance to create fsgd file along with contrasts files. Finally, can I use the qdec gui for this analysis or just the command-line?

Hi Doug, Recently I started working on freesurfer for volume based analysis. For QDEC, I need to include more than 2 variables. For example if I include patients who hail from different places like statutory town, census town and rural. In present scenario, can I include all three as covariates. Here is the error that qdec showing while running GLM: "ERROR: Subject 2 seems to have a mismatched number of discrete factors (expected 4, found 1)" "Reading source surface /usr/local/freesurfer/subjects/fsaverage/surf/lh.white ERROR: no contrasts specified." "Error in Analyze: command fai;ed mri_glmfit --y /usr/local/freesurfer/subjects/qdec/qdecAnalys/y.mgh --fsgd /usr/local/freesurfer/subjects/qdec/qdecAnalys/qdec.fsgd dods -glmdir /usr/local/freesurfer/subjects/qdec/qdecAnalys/ -surf fsaverage lh -label /usr/local/freesurfer/subjects/fsaverage/label/lh.aparc.label" Could you help us out in this regard. Would appreciate any help!! Korann */ /*
