2.B If the annotations do not automatically load, or you want additional data sets, you can select the annotations you are interested in from the file tree. Open the server folders listed in Data Sources and check the data sets you would like to load (red box). IGB will create place-holder tracks (orange box). Click either of the Load Data buttons (green arrows/boxes) to actually load the data into the view.

Opening your own data files
For every file brounght into opened in IGB, a place holder track is created, to show you where your data will appear when visualized. The data set/file will also appear in the Data Management Table. NOTE: IGB does not immediately display the contents of your file; bioinformatics data files often contain enormous amounts of data, more than any program can display. For example, a single short reads alignments ("BAM") file may contain millions of read alignments. IGB generally sets files to Load Region in View, which allows you to select the size of the region that you are going to load (see Selecting a Region of Interest).

As shown above, you can easily navigate through the folders in the Data Sources and Data Sets sub panel. Simply click the tracks you are interested in loading.
Step 4: Selecting a region of interest (Zooming in)
1. If you're working with large files such as .bam, .sam, .wig, .bedGraph, you should 'zoom in' to a smaller area before loading your data, ie select a smaller region of data to load. To zoom in on a region of interest, you can:

2.
Step 5: Finish loading your data
Load the data for visualization from the Data Access tab either by using the Refresh Load Data button or the refresh load icon for each individual track. Areas that are NOT loaded are grayed out .
Finish loading
zoom in or out to select you region and then load only the data to fill the screen. For larger files, such as BAM or wig (bedGraph) files, zoom in to ~500,000 base pairs before loading. For most other files, you can load the whole file without zooming in. Some file types (primarily sequence files) are automatically set to Chromosome or Genome.
4. Load data with the Load Data button to trigger loading of data into the main IGB display.(as you can see in the place holder tracks).
