[Mne_analysis] Choosing a subset of sensors with a uniform distribution over the head

[dgwakeman at gmail.com]

You could manually copy and edit a full view layout file and just delete sensors according to whatever sampling you want. Then you can view these in mne_analyze or mne_browse_raw. The manual describes the layout files (there are fields for the width and height of each "window"

What I would like to do is take half or even a third of the channels, and plot them at double or triple the size, as in http://i.imgur.com/6wcrNFS.png (which I created by just plotting the even-numbered channels). As you can see from this image, simply selecting the even-numbered channels in my array doesn't give a nice symmetrical or uniform distribution. Is there any way to decimate the channels or to otherwise choose a subset of channels that is uniformly distributed over the head? I asked the Fieldtrip mailing list but that package doesn't appear to have any built-in way of doing this, so I thought I would try here as well.
