You can control IGB from scripts, text files containing simple commands for navigation, loading data, and making snapshots.

To run an IGB script:

  • Open a script file using File > Open. Script files should end with .igb.
  • Click an IGB script link. See: Controlling IGB using IGB Links
  • Drag and drop a script file into an open IGB windowjp

Note: A protoype plug-in enabling python scripts (.py extension) was developed but is not yet released. If you would like to know more, please get in touch.


The script file has a simple, space-delimited syntax. Each command should occupy a separate line.


Open a genome version

Open genome version (e.g., H_sapiens_Mar_2006). Any genome version or synonym that's accepted by IGB is accepted here.

Go back to the IGB start screen.

Return to the IGB start screen.

Go to a region

Go to a region of a chromosome (e.g., "chr1:40000-60000" or "chr1:40,000-60,000").

Add a new data set to IGB's list of active data sets

Load the specified file (identified by full path) or URL into IGB. The data set will appear in the user's Data Management table upon completion.

Remove a data set from IGB's list of active data sets

Change the load mode for an active (opened) data set

Change the load mode for the specified data set or file, identified by full path.


The loadmode command will work for any loaded track. Make sure to load your desired track before calling the loadmode command.

Load data from currently active data sets

This is equivalent to clicking the Load Data button in IGB. This triggers loading of data from the active data sets available in IGB, as specified in the load command.

Make images

Export the entire frame, main view, main view with labels, or sliced view, respectively, to a PNG format file. You must include the full path to the file or IGB will write the file to the location from where you launched IGB.

The filename defaults to "<genome_version><timestamp>.png" if not specified.


The snapshot and snapshotwholeFrame commands only work on Mac and Linux if attempting to export an SVG file.

Select genes

Selects the given gene IDs, which are passed in as a comma-separated list.

Wait (sleep) for commands to finish

Sleep the application for x milliseconds.


IGB is multi-threaded, which means that the user may be able to operate IGB while data are being loaded. If your IGB script includes loading data from remote sites (e.g, RNASeq data from the site) then you should include a sleep command to give IGB time to load the data.


Lines starting with the IGB script comment character '#' are ignored.
