primitive: nw:load
Networks Extension Dictionary
  • No items found

nw:load

nw:load file-name default-turtle-breed default-link-breed optional-command-block

Filetype specific variants:

  • nw:load
  • nw:load-dl
  • nw:load-gdf
  • nw:load-gexf
  • nw:load-gml
  • nw:load-vna

Import the given file into NetLogo. Like nw:load-graphml, the importer will do its best to match node and edge attributes in the file with turtle and link variables in NetLogo. If breed is specified for nodes and edges in the file and exists in NetLogo, it will be used. Otherwise, the default turtle and link breeds are used.

Limitations:

  • Multigraphs are not supported in importing. Even if the file format supports it (and many don’t), only the first link will be used on import. This is due to a limitation in the parsing libraries NW uses. nw:load-graphml does support multigraphs with the normal NetLogo limitation that two turtles can share more than one link only if all the links are of different breeds.

nw:load determines the file-type of given file based on the extension and calls the corresponding load-* primitive on it. Note that GraphML must be imported with nw:load-graphml.

Take me to the full Networks Extension Dictionary.

NetLogo is a programmable modeling environment for simulating natural and social phenomena. It was authored by Uri Wilensky in 1999 and has been in continuous development ever since at the Center for Connected Learning and Computer-Based Modeling.
