To obtain the latest version of Negopy, please write to richards@sfu.ca and tell us a bit 
about yourself, your research, what university and department you are in, and what 
you hope to do with Negopy. Please say more than "I want to test Negopy" or "I am
getting into SNA."

Negopy is now shareware. If you find the program useful, please send a check for a suitable amount written to "SFU-Negopy". Funds received will be used for program development and student assistants. Please send the check to Bill Richards at Simon Fraser University, School of Communication, 8888 University Drive, Burnaby, BC, Canada V5A 1S6.  
 If you do this, a hardcopy printed version of the manual -- easier to use than the pdf version at http://www.sfu.ca/~richards/Pdf-ZipFiles/negman98.pdf -- will be sent to you in thanks. 
Difficulty :Need SNA knowledge

One of the oldest network analysis programs, NEGOPY finds cliques, liaisons, and isolates in networks having up to 1,000 members and 20,000 links. In use at over 100 universities and research centers around the world.
NEGOPY is a discrete, linkage-based program for the analysis of networks. The primary goal of the program is to define clusters of nodes that have more contact with one another than with nodes in other clusters. These clusters are called groups, and are conceptually similar (but not identical) to the "cliques" often referred to in the sociometric literature. NEGOPY also sorts nodes into a number of role categories on the basis of their linkage with one another. Final descriptions of the network and its members are expressed in terms of links between the nodes, rather than in terms of abstract patterns of variance, etc.
