.. class:: infomark

**What it does**

This tool splits the intervals in the input file into smaller intervals based on the specified window-size and window type.

-----

.. class:: warningmark

**Note**

The positions at the end of the input interval which do not fit into the last window or a new window of required size, will be omitted from the output.

**About formats**

**BED format** Browser Extensible Data format was designed at UCSC for displaying data tracks in the Genome Browser. It has three required fields and several additional optional ones:

The first three BED fields (required) are::

    1. chrom - The name of the chromosome (e.g. chr1, chrY_random).
    2. chromStart - The starting position in the chromosome. (The first base in a chromosome is numbered 0.)
    3. chromEnd - The ending position in the chromosome, plus 1 (i.e., a half-open interval).

The additional BED fields (optional) are::

    4. name - The name of the BED line.
    5. score - A score between 0 and 1000.
    6. strand - Defines the strand - either '+' or '-'.
    7. thickStart - The starting position where the feature is drawn thickly at the Genome Browser.
    8. thickEnd - The ending position where the feature is drawn thickly at the Genome Browser.
    9. reserved - This should always be set to zero.
   10. blockCount - The number of blocks (exons) in the BED line.
   11. blockSizes - A comma-separated list of the block sizes. The number of items in this list should correspond to blockCount.
   12. blockStarts - A comma-separated list of block starts. All of the blockStart positions should be calculated relative to chromStart. The number of items in this list should correspond to blockCount.
   13. expCount - The number of experiments.
   14. expIds - A comma-separated list of experiment ids. The number of items in this list should correspond to expCount.
   15. expScores - A comma-separated list of experiment scores. All of the expScores should be relative to expIds. The number of items in this list should correspond to expCount.

**Example**

- For the following dataset::

   chr22  1000  4700  NM_174568 0 +

- running this tool with **Window size as 1000**,  will return::

   chr22  1000  2000  NM_174568 0 +
   chr22  2000	3000  NM_174568	0 +
   chr22  3000  4000  NM_174568 0 +
   
- running this tool to make **Sliding windows** of **size 1000** and **offset 500**,  will return::

   chr22  1000  2000  NM_174568 0 +
   chr22  1500	2500  NM_174568	0 +
   chr22  2000  3000  NM_174568 0 +
   chr22  2500	3500  NM_174568	0 +
   chr22  3000  4000  NM_174568 0 +
   chr22  3500	4500  NM_174568	0 +
