External Email - Use Caution

Hello FreeSurfer Developers,

I attemting to run brainstem/ hippocampus/ thalamus segmentation with FS 7.1 and there seems to be a problem with environment variables. Based on comments on other forums, I cannot install GlibC (if this is the case) since it's a cluster. Are there any methods that can be used to avoid this limitation?
