[FieldTrip] mne source reconstruction

[qi li]

Hi,

Is there anyway to map the source space mesh back to voxel space so I
can use the ft_sourceplot.

After MNE source reconstruction, I have

source =

       time: [1x399 double]
        pos: [8196x3 double]
     inside: [1x8196 double]
    outside: [1x0 double]
     method: 'average'
        avg: [1x1 struct]
        cfg: [1x1 struct]

I have 8196 mesh points but how to map it back to the anatomical voxel
space? Thanks!
