Social Animal Networks
Cuauhcihuatl Vital, Emília P. Martins, Indiana University
SocANet calculates various network metrics from a list of dyadic interactions. With the aid of SocANet, researchers can explore the effects of sampling and group size on metrics for a particular research design. Researchers may want to generate data while varying parameters such as number of actors, number of recorded interactions and percentage of gatekeepers according to their research design. Dramatic changes (increase/decrease) of a metric would suggest a strong sensitivity to certain aspects and indicate whether it is a good choice for particular behavioral questions.
SocANet includes two pieces of software. The first part, written in Java (c), simulates animal interactions under certain conditions. To begin each run of the simulation, the user should provide the list of individual animals (i.e., actors) in a text file (*.txt). The second part of the software, written in R (c), calculates network metrics of all the files at a given location.
· For the java simulator (note, you need to compile the file once you download it; it is not compressed so you can modify it as you wish)
