Dear freesurfer experts,
I have finsihed my lgi analyzes with qdec.
In the next step I want to make a correlation between lgi and cortical thickness. Is this possible with qdec and if it is how can I do that?
Best regards and thanks a lot.

Hi
You should take a look at the tutorial at http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecGroupAnalysis. The next step is to design your correlation or group difference by switching tab and let qdec design contrast vector and fsgd files. The next step before you have finished the analysis is to do a multiple comparison using either FDR or Monte Carlo to remove areas that are not statically significant.

If you want to do a vertex-by-vertex analysis, then you can't use QDEC. You'll have to run mri_glmfit manually and use the --pvr option (Per-Vertex Regressor).
