Introduction to bookmarks in IGB
Bookmarks in IGB allow you to create a shortcut to a specific genomic location and zoom level within a collection of data sets. Bookmarks will be listed in the Bookmarks menu. When you create the bookmark, you will be able to provide any name or descriptor you wish to help you remember what the bookmark is for.

Note: If you need to reset preferences to default, or if you need to clear the cache, your bookmarks will NOT be affected. However, if the entire IGB directory is deleted, or if the bookmark sub-directory is deleted, then all the bookmarks will be lost.
Position & data bookmarks
As of IGB version 6.4 and higher, the expanded Add position & data bookmark function will remember the genomic location, zoom level, all the tracks in view at the time and any changes made to the track(s). This includes color selection, name of the track and/or changes made to graphs such as threshholding. Using the bookmark will open all of the data sets/ data sources to the marked genomic location at the original zoom level (as if Choose Load Mode > Region in View were selected) with color and name adjustments. If you are interested in a greater area than bookmarked, zoom out or chose a new region from Current Sequence and then refresh the relevant tracks.
Much as using an internet browser bookmark will take you to a completely new page, using IGB bookmarks will clear away data from different species and/or genome versions and replace it with the data contained within the bookmark. The one time that IGB does this differently is if the data sets that are open match the same species and genome version in the bookmark; in this case, IGB will just add data sets or sources not already opened and zoom to the marked location. For instance, if you have open the 'TAIR9 ALL' data set from Arabidopsis thaliana, genome version June 2009 and your bookmark was made for the 'TAIR9 mRNA' data set from the matching species and genome version, when the TAIR9 mRNA bookmark is activated, it will add the TAIR9 mRNA data set, zoom in to the location and then display both the TAIR9 ALL and the TAIR9 mRNA tracks.
Position bookmarks
The function Add position bookmark only bookmarks the location data and zoom level; you need to open the associated data sets or sources to use these bookmarks. Using this type of bookmark will zoom in to a genomic location and zoom level within the currently opened data. You may wish to indicate that this is a 'position only' bookmark in the name that you create for this bookmark.
Creating and using bookmarks
To create, choose:
- Bookmarks > Add position & data bookmark
...
Wiki Markup Choose *Bookmarks > \[lorainelab:name of your bookmark\]*
Viewing and editing bookmarks
You can view details about your bookmarks, such as their position, which genome they refer to, or customizations. You can also modify some details, such as the name of a bookmark.

- Right click the selected bookmark or click within the bookmark manager window Bookmarks > Properties.
- The information will appear in tabular format in a new window.
- (Optional) Modify the bookmark details.
- Click Apply Changes or Cancel. Changes will not take effect unless you choose Apply Changes.
