Hi Jen,

you can try to get the line by 'Analyze particles', with suitable values for the size and circularity ranges.
Select the line in a few images with the Wand, do 'Measure' with 'Area' and 'Shape descriptors' enabled in 'Set Measurements' and find out suitable ranges.

In 'Analyze particles', Show=Mask should give you the pruned image.
