mne-python Plot SSP projections issue

Hi,

I am trying to plot some ecg SSP projections, but I'm not sure what i need
to do to pull it off.

the error I'm getting from mne.viz.plot_projs_topomap(projs,
layout=layouts) is

Cannot find a proper layout for projection planar-999--0.080-0.080-PCA-01

I'm making the layout with mne.layouts.read_layout('Vectorview-all'). I
think the problem is that the channel names in the layout have a space
where as the channel names in my projectors do not?
Is there a fix?

Thanks
Luke

Thanks for reporting Luke,

where as the channel names in my projectors do not?

Yes, this will be it, probably we missed considering this viz function
during a recent patch addressing this issue mentioned. I will look into it
now.

Cheers,
Denis

Hi Luke,

meanwhile the fix has been merged and is available on the current dev
master branch; simply type:

$ git clone git://github.com/mne-tools/mne-python.git

and run python setup.py install from the repository or link the mne
directory in your site-packages like:

$ ln -s /mypath/mne-python/mne /my-site-packages-path/site-packages/mne

This has the advantage that you don't need to install each time you pull an
update.

Tip: if you want to know where your site-packages are located run the
following line from the command line:

$ python -c 'import site; print site.getsitepackages()'

In case you face any problem don't hesitate to report.

Best,
Denis
