After you have captured threshold "annotations" from a graph or other set of data, you can examine these "annotations" using all of the tools in IGB for working with and comparing annotations.
Getting details about a graph
Textual information about some graphs is available in Selection Info.
Click the colored bar at the left of the graph, then click the Selection Info tab. Resize the columns if needed.
Saving and bookmarking graphs
Most graph properties that you set in IGB can be captured for future use by saving or bookmarking.
Saving graph data as a file
You can save a graph as a separate file for future reference or off line use. Note that this saves only the graph data, without any visualization customizations you may have made to it.
To save graph data to a file:
- Select the graph by clicking the colored bar at the left end of the graph.
- Click the Graph Adjuster tab. Click the Save button.
- Specify location and graph name.
- Pick one of the graph formats offered. Typically choose ".egr" format for interval graphs and ".sgr" format for other graphs.
- You will be prompted to add the proper ".sgr" or ".egr" filename extension depending on the type of graph data.
- Click OK.
Graph properties, such as color, scale, and so forth, may not be saved along with the data. Some graph formats, such as ".bed", ".gff", and ".wig" allow such properties to be specified in "track lines".
Bookmarking graph views
By creating a bookmark, you can save a link to your graph along with the customizations you have made to its appearance. See Bookmarking on page 75.
You can also export your list of bookmarks to share it with other users. If your bookmarks contain links to graph files on your file system, those files may not be available to users on other file systems.
Printing graphs
To print directly to your printer:
- Choose File menu > Print.

- Choose File menu > Export.
- Choose to export either the Main View or Main View (With Labels)
