usage: qnoise.sh -f <input JSON noise spec. file> -o <output file>
All the options:
 -f <file>          Input JSON file path.
 -help              Print this message.
 -o <output file>   Output file path.

Currently Qnoise supports the following types of noises

• Missing value noises (null).
• Duplication noises.
• Inconsistency noises based on certain contraints.
• Outlier value noises.

A simple example of generating duplication spec. is as following

{
    "source" : "test/src/input/dumptest.csv",
    "noises" : {
        "type" : "m",
        "granularity" : "cell",
        "percentage" : 0.2,
        "model" : "r"
    }
}

More details on the usage can be found in the examples or the document.
