Please note there was a problem with the Polhemus digitizer this morning, where it was not localizing properly and always giving errors (> 5 mm) for repeated points. I was not able to reproduce the issue after, i.e. it works ok now. As always, be very careful with the parts, always hanging the cables and placing them in the basket when not holding them. A single fall on the floor can be enough to break the stylus or goggle receivers.
Please let me know if/when this issue reoccurs. If it does, try turning off and on the digitizer (and “start over” in the Brainstorm Digitize panel).
Note the other possible causes of issues in this previous post.
