.. class:: warningmark

**WARNING: This tool breaks column assignments.** To re-establish column assignments run the tools and click on the pencil icon in the latest history item.

.. class:: infomark

The output of this tool is always in tabular format (e.g., if your original delimiters are commas, they will be replaced with tabs). For example:

  Cutting columns 1 and 3 from::

     apple,is,good
     windows,is,bad

  will give::

    apple   good
    windows bad

-----

**What it does**

This tool selects (cuts out) specified columns from the dataset.

- Columns are specified as **c1**, **c2**, and so on. Column count begins with **1**
- Columns can be specified in any order (e.g., **c2,c1,c6**)
- If you specify more columns than actually present - empty spaces will be filled with dots

-----

**Example**

Input dataset (six columns: c1, c2, c3, c4, c5, and c6)::

   chr1 10   1000  gene1 0 +
   chr2 100  1500  gene2 0 +

**cut** on columns "**c1,c4,c6**" will return::

   chr1 gene1 +
   chr2 gene2 +

**cut** on columns "**c6,c5,c4,c1**" will return::

   + 0 gene1 chr1 
   + 0 gene2 chr2


**cut** on columns "**c8,c7,c4**" will return::

   . . gene1 
   . . gene2
