Thank you for your continued support.
I have a question. I used revopoint to digitize the EEG sensor and the shape of the subject's head following the tutorial.
Could you please tell me how to import the EEG data?
You need to link the raw recordings. you can check out this EEG tutorial, while it is based on epilepsy data, it can give you some insights on accessing the recordings, importing, pre-processing, etc.

Thank you for your instructions.
When digitizing with revopoint, after importing the EEG data, should I follow the steps shown in the screenshot below to import the data digitized with revopoint?
@chinmay.chinara, can you address this question?
@rpa19008, please do not repost a question to put in on top of the board. We answer all the posts as fast as we can.
@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.
@rpa19008, please note that the steps provided in the post above will ONLY import the EEG positions, the additional digitized head points (all around the cap to capture the subject's head shape) will NOT be imported. So processes like refining EEG-MRI co-registration using head points will not be available.
You can import those additional head points with:
Right-click on the channel file then Digitized head points > Add points... and select the .pos file.

I apologize for reposting my question the other day.
I also appreciate your very helpful advice regarding the answer.
I may have further questions in the future, so I look forward to your continued support.
@rpa19008, no worries. The trouble with reposing is that it disperse questions on the same topic across different threads, so it becomes more difficult to find for other users to find the answer.
Absolutely, and we are looking forward to answer them
