Hi Martin,
the control points won't hurt the aseg unless you actually put them in the
basal ganglia or thalamus. As long as they are clearly in wm you should be
fine.

Hi, I'm using a lot of control-points (typically 200-500) to compensate for
intensity inhomogeneities in my images.
This tends to create a rather uniformly looking white matter without any
clearly discernible anatomical landmarks, such as the basal ganglia, etc.
Does this mean that the subcortical segmentation won't work properly? Will
this munificent use of control-points constitute a source of error for the
cortical segmentation, or are the protocols relatively robust?
Thanks,
