[Mne_analysis] mne-python: simple topographic plot

[Denis-Alexander Engemann]

Hi Emanuele,

take a look at this PR by Alex:
https://github.com/mne-tools/mne-python/pull/392

and this one by Christian:
https://github.com/mne-tools/mne-python/pull/404

It shouldn't be difficult to merge this soon and add it as an alternative to the viz module.
However it seems the focus has been put on other things in the last months, especially as nobody asked for this.
We now have a good reason for speeding up ;-)

Cheers,
Denis

Hi,

First of all thank you for mne-python: it is very well done and effective!

I'd like to create simple topographic plots from the results of statistical
tests that I am conducting on gradiometer data (evoked responses) of our Elekta
Neuromag. From what I see in the documentation many rich functions are
available in the mne.viz module but I cannot find the simple one that given a
coefficient for each channel (e.g. t-statistic between two conditions) and a
layout ('Vectorview-grad.lout', in my case, if I understand correctly), plots
the topography like

http://fieldtrip.fcdonders.nl/_media/tutorial/eventrelatedaveraging/topoplot_fic_3feb09_erf.png

or like this mne-python plot, but without clickable sensors and timecourses:

   http://martinos.org/mne/auto_examples/plot_topography.html

...a simple colored box for each channel would suffice.

Any hints?

Best,

Emanuele
