Hello, I am running both longitudinal and cross-sectional FreeSurfer (version 7.4.1) on a dataset which includes participants with significant levels of atrophy.If I run the 'default' versions, I see many errors in segmentation and cortical surfaces during QC afterwards (mostly related to undersegmentation of gyri). We want to avoid having to add manual corrections. Therefore, I wanted to ask what the recommended settings are for running FreeSurfer on these populations (eg adding the -bigventricles or -seg-wlo flags?) Thanks!
