.. class:: warningmark

Make sure that the genome build of the input dataset is specified (click the pencil icon in the history item to set it if necessary).

.. class:: warningmark

This tool will only work on interval datasets with chromosome in column 1,
start co-ordinate in column 2 and end co-ordinate in column 3. BED comments
and track and browser lines will be ignored, but if other non-interval lines
are present the tool will return empty output datasets.

.. class:: infomark

**What it does**

This tool converts coordinates and annotations between assemblies and genomes. It produces 2 files, one containing all the mapped coordinates and the other containing the unmapped coordinates, if any. 

-----

**Example**

Converting the following hg16 intervals to hg18 intervals::

    chrX  85170   112199  AK002185  0  +
    chrX  110458  112199  AK097346  0  +
    chrX  112203  121212  AK074528  0  -

will produce the following hg18 intervals::

    chrX  132991  160020  AK002185  0  +
    chrX  158279  160020  AK097346  0  +
    chrX  160024  169033  AK074528  0  -
