Introduction
You can control IGB by embedding IGB links in Web pages. This is useful when you need to manually inspect a large number of regions. By clicking links in an IGB links page, you can quickly move to a new region.
IGB links syntax
When IGB launches, it starts a "bookmark server" at localhost, port 7085.
| Info |
|---|
If you launch a second instance of IGB while one is already running, the new instance will listen to a different port. For this reason, bookmark links will only work for the first IGB instance only. |
IGB uses this internal server to handle HTTP requests.
An IGB link base URL is structured as
| Code Block |
|---|
http://localhost:7085/UnibrowControl?[parameter] |
Show a region
IGB link syntax to show a region is:
| Code Block |
|---|
http://localhost:7085/UnibrowControl?version=[version]&seqid=[seqid]
start=[start]&end=[end]
|
Parameters include:
- version - genome version
- start - start position of the region to show
- end - end position of the region to show
- seqid - chromosome sequence
Example:
| Note |

Other parameters are also available. If you're developing IGB links, it helps to open up an exported IGB bookmarks file in a text editor and take a look at how the links are structured. |
Other options
Scriptfile
As of IGB 6.3, you can use the scriptfile parameter to send commands to IGB, where scriptfile designates a local file or URL
