**WARNING:** Be careful not to concatenate queries of different kinds (e.g., sequences with intervals). This tool does not check if the queries being concatenated are in the same format.

**Example**

Concatenating Query::

    chrX  151087187  151087355  A  0  -
    chrX  151572400  151572481  B  0  +

with Query1::

    chr1  151242630  151242955  X  0  +
    chr1  151271715  151271999  Y  0  +
    chr1  151278832  151279227  Z  0  -
    
and with Query2::

    chr2  100000030  200000955  P  0  +
    chr2  100000015  200000999  Q  0  +

will result in the following::

    chrX  151087187  151087355  A  0  -
    chrX  151572400  151572481  B  0  +
    chr1  151242630  151242955  X  0  +
    chr1  151271715  151271999  Y  0  +
    chr1  151278832  151279227  Z  0  -
    chr2  100000030  200000955  P  0  +
    chr2  100000015  200000999  Q  0  +
