[Mne_analysis] ValueError: stc not compatible with source space.

Hi

How can I overcome this error when running mne.extract_label_time_course?

---
ValueError: stc not compatible with source space. stc has 4097 time series but there are 4098 vertices in source space

It seems to me that the problem originates from mne.make_forward_solution:

Source spaces are in head coordinates.
Checking that the sources are inside the bounding surface and at least 5.0 mm away (will take a few...)

Thank you for waiting.

So can't extract_label_time_course be executed when the number of grid in SourceEstimate(originally Forward model) does not match the number in SourceSpaces? Is there any way to get around this?
Thanks.


Best,
Yuki
