# Creating Custom Tracks

### Data Formats

* A wide range of data formats can be converted to custom tracks than can then be visualized and compared to other genomic data.
* Custom tracks are managed through the "My Data --> Custom Tracks" window. Select this page.
* Available formats for custom tracks are described [here](http://genome.ucsc.edu/cgi-bin/hgCustom).

### Creating a custom track

* Paste the following block of text into the Paste URLs or Data window and click the Submit button. Then select the "view in Genome Browser" option on the next page.

```
track name="ClassExample" description="Edited" visibility=0 url= 
chr4	133149358	133149958	Example1	10	+
chr4	133149754	133149980	Example2	100	+
chr4	133150808	133152008	Example3	500	+
chr4	133152429	133152829	Example4	1000	+
```

* Note the presence of the group "Custom Tracks" with the track "ClassExample". Toggle the display mode to full and click Refresh. Zoom out do that all 4 Examples are visible.
* Select "Tools-->Table Browser". The region will usually correspond to the part of the genome visualized in the browser. Select the “summary/statistics” function to display some statistics about the information in the custom track.
