We post here his question and our answer detailing how IBPindex detects the different tracks present in a file.
Our user's question:
The route is not complete. The arrival displayed is not the real end. It should be the same as the starting point.
IBPindex has a detection system that looks for the different tracks that can be at the same file. In your case, there is a separation of nearly 1.5km between two of the recorded points, they are considered as belonging to two different tracks, and system analysis only the first part of the file.
I send you the modified track, adding some points so that there is not such a big separation between them.
