.. class:: infomark

**TIP:** If your data is not TAB delimited, use *Text Manipulation-&gt;Convert*

-----

**What it does**

You can enter any value and it will be added as a new column to your Query

-----

**Example**

If you original data looks like this::

    chr1 10  100 geneA
    chr2 200 300 geneB
    chr2 400 500 geneC

Typing **+** in the text box will generate::

    chr1 10  100 geneA +
    chr2 200 300 geneB +
    chr2 400 500 geneC +
     

You can also add line numbers by selecting **Iterate: YES**. In this case if you enter **1** in the text box you will get::

    chr1 10  100 geneA 1
    chr2 200 300 geneB 2
    chr2 400 500 geneC 3
