I am working with a longitudinal design (before and after treatment), and based on the website's recommendation (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalEdits)

editing the Base could be enough for this.

If I understand this right, I should generate the Base image (without editing the two Cross images) and then edit the Base only.

After that, I could create the two longitudinal runs (Long) without editing them as well.

Did I get this right?

This could save a huge amount of time since I should edit one image (Base) instead of two (Cross images).

I am using Freesurefer 7.1.1.
