@ParkvilleGeek @bttyeo Totally agree on how scanning time is overlooked in sample size calculations! I simulated multiple DTIs during one scanning session for lower sample sizes (or earlier detection of changes) in motor neuroscience disease https://t.co/

What can one do about that? First during the planning phase of a longitudinal study: Know your math and avoid specific scheduling scenarios: https://t.co/g9HoNvwJqx 4/x
