Hi freesurfer experts,
I am working on a project, and I have used mri_glmfit to compare the cortical thickness of the patient cohort with that of the control. When I examined the results, I noticed some unexpected clusters of atrophy and wanted to investigate which subjects contributed to each cluster. In the previous version, I could do this easily with QDEC, but unfortunately, my current computer can’t set up QDEC because the Windows version is not compatible with FreeSurfer 6.0. I hope you can help me with an alternative method for performing this analysis, as it would be greatly beneficial for my project.
Sincerely, Henry

right, we don't support qdec anymore. Try using mri_glm fit (eg, https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MultipleComparisonsV6.0...)
