A Windows-compatible tool to analyze ecological flow networks.
EcoNetwrk is based on Netwrk 4.2 by Robert E. Ulanowicz (http://www.cbl.cees.edu/~ulan/ntwk/network.html). EcoNetwrk performs all of the analysis of Netwrk 4.2 but in a windows friendly environment. Netwrk 4.2 is copyrighted (1982, 1987, 1998, 1999) and was used with the author's permission and guidance.

User's Manual (MS Word, 12 December 2006)
Input: Standard SCOR-format file, comma-delimited csv file, EcoNetwrk file
Output: The current version of EcoNetwrk produces output in the same format as NETWRK 4.2
User notes: EcoNetwrk is a tool designed to make it easier to use the Ulanowicz NETWRK model. It currently opens SCOR or CSV files, checks for a balanced network, balances the network using DATBAL, executes the analysis, and automatically saves the output as 'DEFAULT.OUT' in the folder where EcoNetwrk resides. Interactive data entry is also permitted. A number of options are available (intermediate steps) on the 'Calculate' menu. EcoNetwrk is compatible with Windows 95 and above. Graphical display of output is a desired later stage of this project. A brief User's manual is included with the installation package. Your comments will help us improve the documentation.
