Graphical Fragment Assembly. A Comparison between a traditional graph and a GFA. Circles represent nodes, rectangles—segments, lines are connections. B Incomplete assembly of ARG (not all fragments are linked). C Simple linear assembly from an ARG seed. D Complex branched assembly around ARG. E Zoom-in on the fragmented seed ARG assembly from panel D. Segments originated from an ARG seed are highlighted green. Gray segments represent anextension of the assembly beyond the seed sequence. Here and in the following figures, GFA are visualized using the Bandage tool [18]
