Ensure that your file is in a format we support
IGB can open and read nearly all of the common data and graph files used with genomics data. For more information about supported file types, please see File Formats. We also take requests - if you would like us to support a new type of file format, please let us know.
Refresh your data
IGB allows you to open files from your desktop, local servers, URLs or other data sources. This can be done through File>Open, or by simply dragging and dropping the file or URL into the IGB display. However, if the file contains a lot of data, IGB will not instantly start loading the data into the display.

IGB can readily display alignments data from .bam files. However, it requires a .bam index file (called a .bai) to be present in the same folder as the .bam file. For more about creating .bam and .bai files, please see Making BAM Files for IGB (RNA-Seq).
I opened my sequence file (".fasta" or ".bnib" or "twobit") but all I see is a gray bar and dashes.
When you open a "fasta" (or other sequence) file, and if you have not already selected a species and genome, then IGB will read the file and construct a new genome, using the names of the sequences it finds in the file.
