Can you post the electrodes.csv file that you are using? If you're using freesurfer locations, they should work
Thanks @droyston ,
This is a good question. We are using tkrRAS
coordinate.
Please check freesurfer document on how to transform from scanner or MNI305 to tkrRAS.
TalXFM
, Torig
and Norig
can be obtained via rave
code in R:
# Change project/subject to project and subject
brain = rave::rave_brain2("project/subject")
# Talairach
brain$xfm
# Norig
brain$Norig
# Torig
brain$Torig

Yes I can, the file is attached (converted to txt because the comment doesn't appear to support csv)
These values are really tiny... how did you extract these? Perhaps they are fractional values of the total space? You could try multiplying them by 256 and see if that fixes the problem

These coordinates are extracted from the coregistered channel objects in Brainstorm, and appear to align correctly in Brainstorm's surface-viewer
I am trying to add electrode coordinates in the electrodes.csv meta file, using the individual-space coordinates compatible with the Freesurfer reconstruction, but the RAVE render shows all electrodes at a single point near the origin of the render space. Which coordinate frame/range of locations does RAVE expect?
