Multiple Relations Networks Networks containing multiple relations on the same set of vertices, e.g. Sampson monastery data from Ucinet dataset - Ucinet DL file Defining multiple relations networks in Pajek input files: *Arcs/*Edges format *Arcslist/*Edgeslist format *Matrix format Basic information Info/Network/Multiple Relations - number of arcs/edges in each relation. Visualization of multiple relations networks: Options/Colors/Edges/Relation Number and Options/Colors/Arcs/Relation Number - colors of edges/arcs are determined by relation number Options/Colors/Relation Colors - color table for relation numbers. Options/Lines/Draw Lines/Relations - showing/hiding lines belonging to selected relations e.g. 1-3,6,10-15. Export to SVG / Kinemage. Net/Transform/Multiple Relations/Extract Relation(s) - extracting selected relations from multiple relations network. Combining ordinary networks on the same set of vertices to MRN Net/Transform/Multiple Relations/ Change Relation Number - Label and after that Nets/Union of Lines. Net/Transform/Multiple Relations/Canonical Numbering - enumerate relations with numbers 1, 2,.... Net/Transform/Multiple Relations/ Relation Numbers->Line Values. Trick: use this option, then Net/Transform/Sort Lines/Line Values/Descending and draw the network, export to EPS or SVG. Example multiex.net. Net/Transform/Multiple Relations/ Line Values->Relation Numbers - since multiple relations were not available in older versions, we used line values to distinguish them. Important: partition of lines can be coded as a multiple relations network. Biconnected components is a partition of lines. Example write.net. Edit/Network contains relation number of each line - possibility to change it. Genealogical networks (Ore, pgraph, bipartite pgraph) are multiple relations networks. Temporal networks containing multiple relations described using time events, example sample TIM file.
