.. class:: warningmark

This tool currently only works with ENCODE data from genome builds hg16 or hg17.

-----

.. class:: infomark

**Note:** If you do not wish to mask a set of intervals, change the Use Mask option to No, this option will override any Mask files selected.

-----

**Syntax**

This tool will attempt to create a random set of intervals that mimic those found within your source file.  You may also specify a set of intervals to mask.

**Allow overlaps** options
  * **Across Strands** - random regions are allowed to overlap only if they are on different strands.
  * **Any** - all overlaps are allowed.
  * **None** - no overlapping regions are allowed.

**Regions to use** options
  * Bounding region of interest based on the dataset build.
