Hello，I have a question about source localization of EEG. When calculating the head model with OpenMEEG, it often takes a long time. I've seen on the internet that it can be reused. So, I directly copied the head model file calculated by OpenMEEG to another EEG file waiting for source localization. Is this correct?
How long is it taking for your computation?
You can reuse the same head model if and only if you are using the same subject with the same anatomy and number of EEG channels [amount and position].
Thank you for your reply. It will take about half an hour to calculate the head model.
It might be because my computer‘s computing power is not very strong.
30min is okay, maybe you can reduce the resolution of the BEM surfaces.
as reported in previous post, if you are using the same subject, with the same anatomy and channels, so you can reuse the head model.
