Currently it is not possible to generate freeform labels by, e.g., using a mouse cursor to draw on the cortical surface. One option is to read labels from a known cortical parcellation, using [mne.read\_labels\_from\_annot()](https://mne.tools/stable/generated/mne.read_labels_from_annot.html#mne.read_labels_from_annot). Another option is to start with a seed vertex and grow the label spatially using [mne.grow\_labels()](https://mne.tools/stable/generated/mne.grow_labels.html#mne.grow_labels). A third option is to start with an existing SourceEstimate object, and create a label from any non-zero vertices in it, using [mne.stc\_to\_label()](https://mne.tools/stable/generated/mne.stc_to_label.html#mne.stc_to_label). Note also that labels can be combined using the `+` operator, so you could for example use `grow_labels()` to create several and then merge them into a single label using `+`.

This should be possible using FreeView though, right? (It’s been a while since I last looked into this.)

it’s possible with mne\_analyze (mne-C command)

Yes, I think FreeView allows this. I think there’s also a way to do this from MNE-C.
