Introduction

The IGB Sequence Viewer gives users the option to view a region of sequence in a separate window with many options. The viewer will display the nucleotide sequence of selected sequence, exons, gene models, cytobands, or short reads. displays sequence data in a text-based window. When you right-click a selected item in the display, such as a gene model, you'll see main display window or select a region of genomic sequence, IGB displays a menu offering View Genomic Sequence. Alternatively, you You can access the same command from functionality using the View menu.

The viewer also has a variety of ways offers options to display protein translations , and the ability to copy/export nucleotide sequence, annotated nucleotide sequence, protein sequence, etcreverse complements. You can also copy the sequence to the system clipboard.

View Sequence

By default, the viewer depicts bases in yellow on a black background. Use the Colors menu to change the color scheme to Blue on white (exons in blue and introns in black)

...

You can look at the selected sequence highlighted in the refseq, or (if present) the sequence of DNA contained in a cytoband. While this method loses the advantage of annotations/ exon designations, it does allow you to select DNA from introns, upstream and downstream regions, or any other area which may contain sequence of interest (i.e. promoters, enhancer binding elements, etc.). Select the sequence you wish to view by click-dragging the cursor over the sequence bar at any zoom level. A red outline will appear around the selected sequence.
