For a current study, I have a few subjects who had to come back for a second session, which means they have two sets of anatomy files that I will be manually warping independently. I just nudged the first sessions anatomical data to the first sessions functional data and warped the anatomy. The problem is after nudging the second session anatomy to the second session functionals, it won't let me tick Allow edits to set markers for warping the second session anatomy. I have all of the data in one folder currently. I tried moving the second session data to another folder, but I still get the same error. Am I missing something? How can I allow edits on this second dataset?
