Dear Doug & Bruce, It's indeed a confusing situation. What it boils down to is:
- I scanned the polar angle session and the eccentricity session on different days - I had defined V1-3 already based on the polar angle session before scanning eccentricity - All data from the polar angle session were lost, apart from the V1-3 labels I made and the anatomical (not inflated) - Since I now didn't have an inflated brain anymore, I inflated the anatomical from the eccentricity - When I tried to overlay the labels onto this newly inflated brain, the labels were not correctly displayed I just tried again by inflating the anatomical from the polar angle session (instead of eccentricity), and when I use tksurfer P2_BK lh inflated -reassign the labels are displayed correctly, so that's great news! However, when I display my eccentricity data, with tksurfer-sess -c eccen -fthresh 0.5 -a rtopy.self.lh.eccen -s P2_BK, the labels are wrong again. Adding -reassign doesn't work in this command (flag not recognised). So at least I could open two terminals, one to display the inflated brain with correct labels, and one to display the eccentricity data. This is of course not ideal if I want to draw labels on the eccentricity screen using the labels displayed in the other screen as a boundary. So if anyone has an idea how to get the labels to be displayed correctly with the tksurfer-sess command please let me know. In any case, thank you all for your help so far!
