[FieldTrip] segmentation and individual grids

Dear Ali, Dear JM,

thanks a lot for your help.

According to your suggestions I have modified
my code as following:

mri = ft_read_mir('MRI_FILE_V2.mri');

cfg = [];
cfg.downsample = 2;
cfg.coordsys = 'ctf';

mri = ft_volume_downsample(cfg,mri);

cfg = [];
cfg.coordsys = 'ctf';
seg = ft_volumesegment(cfg,mri);
seg.anatomy = mri.anatomy;

Now the comparison of the segmented volumes and the MRI look fine,
but it seems that there is still a problem when I compute the individual grids (see attached figure).

I am also attaching the code I am using.

Would be great if you could help me to get this working.
