Take a look at your data. Make sure there are no \t's anywhere or any other characters that might cause the input to fail.
Using your own data with DGA is simple! Make sure the file is an edge list of the following format.
It must be a character separated file, so you can use commas, TABS, etc. If you use anything other than the default, then you must let us know via a configuration value.
Bug Reports can be submitted here. We will try and get it resolved as soon as possible!
