Dear Cui Yi,

please see here and download the three files provided there. It is a config file (that contains all important configuration parameters for a simple accessibility computation), a network file and a facilities file (that contains some work facilities). Just put all three files in the same folder (the network and the facilities file are then referenced correctly by the config file) and try to run again.

You should get output under 'work/accessibilities.xml' with work accessibility values of four locations.

Let me know it you run into any other problems.

Dominik
