No, not needed, if you are only working with subcortical volumes.

Quick question. For my specific analysis, I’m most interested in the values given in the aseg.stats file. I’m comparing gray matter volumes from specific ROIs between patients and healthy controls. Thus, the outcome measures I will be reporting are things like: left caudate volume is 75 +- 11 units for controls, 52 +- 6 unit for patients. I am not particularly interested in each subject’s individual 3D reconstruction.
For each subject, I have verified that tal registrations, pial surface boundaries, and WM segmentation boundaries are roughly accurate based on a quick assessment, e.g. no gross image registration errors have been made.
Given that the reconstruction itself is not of interest, is it still advised to make edits to the recons in order correct small inaccuracies?
Thanks so much or your help!
Best, Kamy
