how to identify labels for source activity

hi,

taking a deeper into mne python finally and so far i like it very much.

one question has come up so far. lets say i found some effect in source
space: is it possible to get the label (of some atlas) that is
associated with that area?

and a quick second one: is there some way to visualize all the
freesurfer atlases in a way that i can get labels for areas? i.e. i have
some kind of surface plot, the atlas parcels are colorcoded and when i
click on one of them, it tells me the label?

thanks in advance!

I don't think we have a function for this but it should not be hard given
an stc vertno to match it to a freesurfer annot.

and a quick second one: is there some way to visualize all the
freesurfer atlases in a way that i can get labels for areas? i.e. i have

you can view an annot with pysurfer as here
https://pysurfer.github.io/auto_examples/plot_parcellation.html

but it's not interactive presently.

Hi Thomas,

Perhaps this one does what you are looking for with regard to the first
point:
