Difference between sensorLayout.xml and coordinates.xml #42

Closed const7 closed 2 years ago

const7 commented 2 years ago

Can you tell the difference between these two files? It looks very similar. And also, what do these files correspond to when loading into EEGLab's EEG struct? Thank you.

These are MRI files. The plugin is about EEG. Look at this page for more info https://bids-specification.readthedocs.io/en/stable/

Sorry for the possible misleading. These two are files under the EGI/Phillips .mff file folder like this:

I'm quite confused about them since they both have x, y, z like coordinate fields. image

It seems that coordinates.xml is imported to EEG.chanlocs. But if .mff already has location information what does the standard channel location file (like GSN128.sfp, GSN129.sfp) in eeglab do?

Thanks again for your time!
