Pulling epoched data from specific vertices

Hi MNE users,

I have 40 ROIs with which I am trying to run a single-trial granger
causation analysis on. Instead of pulling all of the data from each
ROI, I am hoping to find a command that will return the vertices list
within an ROI. Is there such a command? In addition, is there a
command that will return the epoched data from a vertices list after
specifying the condition? Originally I was using
mne_compute_raw_inverse specifying an ROI and then mne_epochs2mat to
pull the data. But, it will be much more efficient if I can just input
the vertices that I need. Thanks in advance.

Best,
Corey

Hi Corey,

To get the list of vertices, simply load the label in matlab (it is
just a list of vertices).

I personally haven't done this, but I assume that the --label option
in mne_compute_raw_inverse should do what you want.

Hi Dan,

Thanks for the input. Let's say I have my list of selected 40
vertices, 1 from each label. I would like to use a command that pulls
out the epochs from these 40 vertices. Is this possible? It seems like
the --label with mne_compute_raw_inverse will not let me do this as
with this command I am supposed to input an ROI and not a list of
vertices. Thanks in advance.

Best,
Corey
