BIOSEMI 128 Channel File

Bugs
1

Hello,

I have been trying to import the channel file for the BIOSEMI 128 10-20 system into Brainstorm. I have primarily been using Robert Oostenveld's website here as a resource; I have already tried importing the coordinates from 'sphere1', 'sphere2' (which was the file intended for source localization), and 'realistic'. However, when displaying the sensor locations on the default brainstorm anatomy cortex model, they are misaligned in all three cases (shown below). I was thinking of just shifting them manually somehow, but was just wondering if anyone has any suggestions?

Hi @jonathanhy314

It seems that the coordinates system of the channel files is not aligned with the default anatomy in Brainstorm. I don't know what is the coordinate system is on Oostenveld's website.
If you need just the channel file, Brainstrom already has the BioSemi channels,
On the functional tap, right-click on your subject, and then > Use Default EEG cap => then select your model.
