Hi Bechir,
now it seems that there’s some problem that the algorithm can’t find the trajectory.
What you could do is:
1. Set the Entrypoint to manual. You’ll be prompted to click on the electrodes. Do you see them at all? Has the data been properly normalized?
2. Instead of “auto” in mask size, you can try to enter a number between ~ 7 and 15. This keeps the mask size fixed and helps in some cases.
What dataset are you using? Is it T1-weighted data? Because here, the algorithm sometimes gets lost in the ventricles. If you have a different dataset, maybe try to skip this patient first. I totally need to upload an easy sample dataset one day.
I hope this helps.
Best, Andy
