Mne-python: plot_sensor_connectivity

[BarryLiu97]

When I ran plot_sensor_connectivity.py in cmd, the figure just appeared less than 1 sec, then it was gone.

matplotlib figures are non blocking by default so it appears and closes.

you need to use block parameter in matplotlib

Also, can you give more details on how you start the script? Because AFAIK, the 3d plots require an interactive python environment.

So python -i ./examples/connectivity/plot_sensor_connectivity.py or run ./examples/connectivity/plot_sensor_connectivity.py inside ipython works for me.

just type 'python plot_sensor_connectivity.py'

[BarryLiu97]

Ok, it works when I added -i

[BarryLiu97]

What does the -i mean?

[BarryLiu97]

And is there any way that we can see the channels' name in 3d?

[BarryLiu97]

OK, it shows the chan name when I use mayavi

[GuillaumeFavelier]

From python --help:

-i     : inspect interactively after running script; forces a prompt even
         if stdin does not appear to be a terminal; also PYTHONINSPECT=x

is there any way that we can see the channels' name in 3d?

It's normally enabled by default but there seems to be a regression for the pyvista 3d backend on the master branch. I'll fix it soon :)

[BarryLiu97]

Can Miyavi make respond to the mouse click? Like only when I click on the electrode, the name shows up.

[GuillaumeFavelier]

This feature is not currently implemented.

[BarryLiu97]

But could Miyavi support this? Recently I was trying to do a similar task but don't know how to start.

[GuillaumeFavelier]

You can try opening an issue on mayavi to ask directly?

We are transitioning out from mayavi in favor of pyvista so I doubt such a feature will be added for the mayavi 3d backend.

[BarryLiu97]

Thanks!

I think this should be part of https://github.com/mne-tools/mne-python/issues/8382 -- once we add sensors to the Brain plot, they should be pickable and when you pick them their information + trace can show up in the show_traces area.
