Introduction
IGB aims to be an integrated genome browser, meaning it can display data from a variety of diverse data sources, all merged into the same view. This includes data sets loaded from your computer, from URL sites, or from various public (and private) DAS, DAS2 and Quickload servers. IGB can also display data from many file types, including:
...
While some file types contain information specifying their species and genome version, most do not. However, if you load a file that has the species and genome information, IGB will open the proper species and genome, even if it is not the one you have chosen.

IGB does NOT immediately display loaded files. Many of today's next-gen sequencing files are too big to display all at once. IGB handles this issue by waiting to visualize data sets until you ask it to load data. |
...
For files loaded from URL or from the local computer, just drag and drop into the IGB interface; the file will immediately appear in the Data Management Table. Alternatively, use the File > Open File.. or Open URL... to find and load the file(s) you want. Be sure to set the species and genome at the bottom of the file selection window.
Data Management Table
IGB is capable of loading and displaying whole genomes, whole chromosomes or just portions of a data file, depending on the file type. Therefore, although there are many load options, not every file type can be loaded the same way. There is always the option of Don't Load, which will simply not load the individual file but will maintain it in the list.

If you set the Autoload threshold too high, IGB will try to load all of the indicated data, which could exceed the memory limit. |

If the data is set to Load Mode > Manual, simply click Load Data. If you want all the tracks to load data at once, use the Load Data button (red box, arrow); to load a single track use the Load Data icon in the Data Management Table (red arrow). Sequence can be loaded from the Load Sequence button (purple box, arrow).
