Sorry this didn’t seem to send the first time due to attachments most likely, so I’ll leave them out and let me know if you need to look at them.

Hi all,
I’m 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’ll post the commands I’m running below. Essentially I’m 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’ll also attach the summary file from mri_glmfit-sim for the cluster and a sample recon-all log.
Any help is appreciated!
