glad it worked.
What you could do is i) try with a “manual” entrypoint, i.e. set the popup menu to “manual” before running the pre-localization step. You’ll be prompted with a window in which you may click on the electrodes within a red rectangle.
If you don’t see the electrodes at all, something went wrong in normalization.
ii) try with another patient – just to verify it works in general on your side. If that works, we can definitely fix it for the current patient, as well.
