**What it does**

This tool splits a file into different smaller files using a specific column.
It will work like the group tool, but every group is saved to its own file.

-----

**Example**

Splitting on column 5 from this::

    chr7  56632  56652  cluster 1
    chr7  56736  56756  cluster 1
    chr7  56761  56781  cluster 2
    chr7  56772  56792  cluster 2
    chr7  56775  56795  cluster 2

will produce 2 files with different clusters::

    chr7  56632  56652  cluster 1
    chr7  56736  56756  cluster 1


    chr7  56761  56781  cluster 2
    chr7  56772  56792  cluster 2
    chr7  56775  56795  cluster 2
