I just loaded up the label on a single subject, looks like it is fine, it's in the same position and squarely on the surface, it's a little skinnier but I'm guessing that's the difference of overlaying it on the subject. We tried looking at the ocn.dat file earlier and didn't find a significant difference between groups despite the output of mri_glmfit-sim (see this thread: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg53380.html)
Have you tried to view your label on the individual subject? If your original analysis was on cortical thickness, then there will be a *ocn*.dat file in the output with the values for each input subject and each cluster
Hi all, I知 trying to extract individual cortical thickness values using the output of the annotation file from mri_glmfit-sim. This worked well for the left hemisphere, we got values that were significantly different between groups we had specified in mri_glmfit, but for the right hemisphere we get all values of 0 for the cortical thickness and mean curvature. I値l post the commands I知 running below. Essentially I知 attempting to take the annot file from mri_glmfit-sim, convert it to a label, then put that label onto a subject (which may or may not be necessary), and pull out the anatomical stats using that label. Below is the example code for one subject. I did also confirm that the initial annot file, and the final subject label both sit on the right hemisphere when loading them up in freeview. I値l also attach the summary file from mri_glmfit-sim for the cluster and a sample recon-all log. Any help is appreciated! - Taylor H.
