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

[Stephen Politzer-Ahles]

Hello,

I am trying to plot a multiplot of MEG sensors over the head, but since I
have over 200 sensors I don't want to plot them all (it becomes more or
less illegible; see http://i.imgur.com/lT93i2T.png). 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 (for example, somehow
using the neighbours structure) to decimate the channels or to otherwise
choose a subset of channels that is uniformly distributed over the head?

Thank you very much,
Steve
