Exception thrown #4

Open petracca opened 7 years ago

petracca commented 7 years ago

Hello,

I am trying to run my own dataset through the tool, but an exception is thrown and I am not sure how to work around -- I believe the format of input file is fine, and I can provide the dataset as a mean to reproduce the issue.

Thank you for any input.

Hi,

if you can provide the dataset I can take a look into the issue.

petracca commented 7 years ago

Hi,

This is an example dataset -- I had to rename as .txt because github would not accept .dat in a post problem.txt

Thank you for your time.

I've added the details on the data input format on the readme. Here they are: 

First line: list of variables names, separated by space;
Second line: list of variables cardinalities, separated by space;
Following lines: list of values taken by the variables in each datapoint, separated by space.

(the value that a variable takes should always be lower that the declared cardinality)
