[FieldTrip] ft_sourceinterpolate with stats data

[Haiteng Jiang]

Hi Andreas ,
    It is annoying that it doesn't work if you specify cfg.parameter 'all'
and I don't know why either. However ,  I have a very simple solution for
this by interpolating 'stat' and  'mask' then combining afterwards when you
want to plot your statistic result. The FT code is something like this:

  cfg                    = [];
cfg.voxelcoord     = 'no';
cfg.parameter      = 'stat';
cfg.interpmethod  = 'nearest';
cfg.coordsys         = 'mni';
statplot                 = ft_sourceinterpolate(cfg, stat,mri);

cfg                                       = [];
cfg.voxelcoord                      = 'no';
cfg.parameter                       = 'mask';
cfg.interpmethod                   = 'nearest';
cfg.coordsys                        = 'mni';
mask                                  = ft_sourceinterpolate(cfg,
stat,mri);
statplot.mask                      = mask.mask;
     Hope this helps.

          Best,
          Haiteng
