I don't know what pathline is. But if you can export your contour lines to a binary image, then you can extract the longest one with bwareafilt
longestContour = bwareafilt(binaryImageOfContours, 1); % Get only the blob with most number of pixels.

I don't know. We're all just guessing here because he doesn't want to share his original data or code for how the vector field was created or how the contour lines were created. Obviously trying to figure it out from a screenshot is not the best way, and susceptible to the size of the plot on screen, but he's not sharing anything else so what can we do? We have no context at all other than it's a vector field. I'm going to quit soon unless more helpful information is forthcoming.
@Suman If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
