Dear Prof. Fischl Thanks for the prompt response.
The more specific reason of my query is that there was a difference in statistical significance between two FS versions. For example, the result of group comparison of left thalamic volumes (ANCOVA controlling for age and eICV) is statistically significant (p = 0.04) when using FS 5.1, whereas the result is no longer significant at all (p = 0.28) in case of FS 5.3. I'm a little confused about this discrepancy. Which result should I trust? Thank you in advance for your comments.
