I am having trouble with segmenting an MRI. I am using the ‘draw’ tool in the ‘Segment editor’. I draw the outline you can see in this picture:
And when I press enter, this is what I get:
As you can see, there are unsegmented vertical lines that should be filled. In addition, some filled vertical lines show up in the next slice. I segmented one slice every three slices and this is what I get in the axial plane (see green lines on the left):
My guess is that this error is related to the orientation of the slices or something like that. Can someone help?
