**What it does**

This tool merges columns together. Any number of valid columns can be merged in any order.

-----

**Example**

Input dataset (five columns: c1, c2, c3, c4, and c5)::

   1 10   1000  gene1 chr
   2 100  1500  gene2 chr

merging columns "**c5,c1**" will return::

   1 10   1000  gene1 chr chr1
   2 100  1500  gene2 chr chr2

.. class:: warningmark
   
Note that all original columns are preserved and the result of merge is added as the rightmost column.
