NAME

	socnetv - Visualize and analyze social networks

SYNOPSIS

       socnetv < file.net >

       socnetv -V | --version

       socnetv -h | --help

DESCRIPTION

       Social  Networks Visualiser (SocNetV) is a flexible and user-friendly tool for Social Networks Analysis and Visualisation. It lets you con-
       struct networks (mathematical graphs) with a few clicks on a virtual canvas or load networks of various formats (GraphViz,  GraphML,  Adja-
       cency, Pajek, etc) and modify them to suit your needs.

       The  application  can  compute  basic  network properties, such as density, diameter and distances (shortest path lengths), as well as more
       advanced structural statistics, such as node and network centralities (i.e. closeness, betweeness, graph), clustering coefficient, etc.

       It supports various layout algorithms (i.e. Spring-embedder, circular and in levels according to various centrality indeces) for meaningful
       visualisations  of social networks. Furthermore, random networks (Erdos-Renyi, Watts-Strogatz, ring lattice, etc) can be created with a few
       clicks.

       SocNetV is being developed in C++ with the Qt GUI development toolkit. Qt is the only dependency.

OPTIONS

       --version | -V
	      Displays the version of the program.

       --help | -H
	      Displays a short help message.

       file.net
	      The name of the file you want to open.

USAGE

       SocNetV has a simple Graphical User Interface (GUI). The biggest (right) part of the window is occupied by a virtual "canvas" where network
       nodes  and  edges  appear. To the left of it, there is a dock with 4 buttons (add/remove node, add/remove link) and some LCDs which display
       statistics. On the top of the window, you will find the menu with all commands and options, and at the bottom there is a status bar,  where
       messages appear.

       To create a new node, you can double-click on the canvas or click on the "add node" button.

       To  create a new link, you can middle-click on the source node and then on the target node.  Alternatively, you can click on the "add link"
       button from the dock.

       You move a node by left-clicking and dragging it. When you right-click on a node, a context menu appears. From there  you  can  remove  the
       node,  change  its  color,  label, size as well as its shape. SocNetV supports many kinds of node shapes, i.e rectangles, diamond, ellipse,
       circle, etc. A similar menu  appears when you right click on a link.

       Supported Formats

       SocNetV supports many network formats, i.e. GraphViz (.dot), GraphML (.graphml), Pajek (.net), Adjacency matrix (.net, .txt). You can  load
       these  kinds of files by clicking on menu File > Load or by specifying them explicitly at the command line.  SocNetV uses simple inspection
       routines to check the format of the given file. In most cases, it will load the file, no matter what the file extension is.

       Layout algorithms

       SocNetV also supports a variety of layout algorithms, such as spring-embedder (i.e. energy based) and centralities-based. The latter  repo-
       sition  all nodes in circles of different radiuses (i.e. more central nodes appear near the centre of the canvas) or in levels of different
       height (more central nodes appear near to the top).

       You can apply layout algorithms from the menu Layout or by clicking on the checkboxes on the dock. Not all  layouts  appear  on	the  dock,
       though.

KNOWN BUGS

       The network file parser is not 100% trustworthy. For instance, complicated Pajek or GraphML files can crash the application.

       Antialiasing is off by default to boost the speed of node movement. You can enable antialiasing by pressing F8.
