Schematic representation of the sequence-independent loop-building algorithm. Loop candidates {l 1, l 2, l 3, …, l N} are shown with open circles and dashed lines. The most likely loop candidates are built and the loop with the highest ARP/wARP tracing score above a standard threshold is kept (l 2; marked in red in the figure).
