**What it does**

This program detects overlapping indels in a chromosome and keeps all non-overlapping indels. As for overlapping indels, the first encountered one is kept and all others are removed. 
It requires three inputs: 

- The first input is a TABULAR format file containing coordinates of indels in blocks extracted from multi-alignment.
- The second input is an integer number representing the number of the column where indel start coordinates are stored in the input file.
- The third input is an integer number representing the number of the column where indel end coordinates are stored in the input file.
- The output is a TABULAR format file containing all non-overlapping indels in the input file, and the first encountered indel of overlapping ones.

Note: The number of the first column is 1.


**Example**

Let us have the following insertions in the human genome. The start and end coordinates of insertions are on columns 5 and 6 respectively::

        3       hg18.chr22_insert       3       hg18.chr22      14508610        14508612        3924    -       panTro2.chr2b   132518950       132518951       3910    +       rheMac2.chr17   14311798        14311799        3896    +

By removing the overlapping indels which, we get::
