Dear FreeSurfer Team,
I hope you are well. My name is Ted and I am a postdoc working at the UCL, faculty of brain science
I am working with high-resolution T1-weighted MRI data and would like to identify an automated approach to delineate the periaqueductal gray (PAG) and ventral tegmental area (VTA) at the individual participant level.
I was wondering whether FreeSurfer provides:
1) Automated segmentation or masks for PAG and/or VTA 2) If so, how precise these segmentations are (e.g., spatial resolution, validation), and 3) Whether these delineations are available at the single-subject level, rather than only in standard space
If FreeSurfer does not support this directly, I would also appreciate any recommendations for alternative tools or workflows.
Many thanks for your time and help in advance.
Best regards, Huaiyu Liu (Ted)
