hello fieldtrippers,

I recently worked out how to create virtual channels using beamformer and an atlas.

However, now i have the problem of plotting the data using ft_sourceplot.

The atlas has mni coordinates, but the mri headmodel has ctf coordinates.

atlas =

            dim: [91 109 91]
            hdr: [1x1 struct]
      transform: [4x4 double]
           unit: 'mm'
         tissue: [91x109x91 double]
    tissuelabel: {116x1 cell}
       coordsys: 'mni'

mri =

      anatomy: [256x256x256 double]
          dim: [256 256 256]
    transform: [4x4 double]
     coordsys: 'ctf'
         unit: 'mm'
          cfg: [1x1 struct]

Is there a way to change either so that I can plot the data?
