@rpa19008 that is correct and that is one way of doing it i.e. right-click on the channel file BrainAmp channels (65) > Add EEG positions > Import from file and do as you have in your screenshot above to import all the positions from the file 3DScanner_Sub_1.pos saved from Revopoint scan digitization.
There is another way of doing it as well. I believe the Sub_1_20250812_01 (68) in the screenshot above is the channel file saved from Revopoint scan digitization. Since you already have it in your protocol you can right-click the channel file BrainAmp channels (65) > Add EEG positions > From other studies and choose Sub_1_20250812_01.
