External Email - Use Caution
Hi all,
I have a couple of questions regarding fsaverage:
1. Is this file updated every time a new subject is process with recon-all? 2. If I obtain externally preprocessed datasets (e.g., from the 1000 Functional Connectomes Project) should I register those subjects to my local fsaverage? * Ultimately, I would like to conduct an ROI analysis of the differences between normative data from a large online biobank and locally imaged patient population. The workflow for such analysis recommended on (https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI) suggests to draw ROI labels directly on fsaverage (a template to which all subjects run with FreeSurfer have been registered to) and then use the mri_label2label command to map the label to individual subjects. Would this work for both locally and externally preprocessed groups? Thank you,
