Hi everyone,

I would like to extract the source time series from my MEG recording. So far that I am able to do all the required preprocessing steps, including freesurfer cortical reconstruction, and successfully use `mne.minimum_norm.apply_inverse()` to do the inverse operation and get a `stc` file.

I want to extract all the source time series data of a given region (more specifically, auditory cortex).  
The function `mne.extract_label_time_course()` is similar to what I want. However, I want to extract all the individual time series within a given label, rather than just one one averaged time series from a label.

May I ask how could I do it? Many thanks!

Sincerely,  
Andrew

I think [stc.in\_label()](https://mne.tools/stable/generated/mne.SourceEstimate.html?highlight=in_label#mne.SourceEstimate.in_label) is what you’re looking for?

I think it works! Thank you @drammock ! 😃
