Dear Johannes,

With the 'normal' mesh and default value of radius (5 mm) I find proximal vertices for all the locations you specified. The fact that you don't indicates that either you use a different mesh or a different radius. If you increase the radius it should all work OK.

Dear SPM users,

I have some problems using the surce extraction on MEG data.
In general it works but I'm not able to extract some sources. The error message looks like:

Running 'M/EEG source extraction'
No proximal vertices found for source(s) 1   3   8  10  13  18
These sources will be discarded

The coordinates of those sources are:
1 [-52 -42 20]
3 [-40 28 -2]
8 [-4 2 62]
10 [-58 2 4]
13 [40 28 -2]

Any idea why this happens?

Best regards,
