Pan & zoom

Panning is easy if you are using computer with mouse-like pointing device. You can just drag on genome heatmap using cursor and pan. All the genomic feature tracks and statistical tracks will move all together:

In case this panning method doesn't work (like if you're using touch-screen device) you can click « » icons in floating toolbox, and the browser will move its location one entire page upon each click:

If you want to zoom in and see details on an interested region, you can drag on chromosome ideogram around that region, where a transparent blue box will appear:

However, when the browser is at finest level (showing base pair letters on chromosome ideogram), you won't be able to zoom in anymore. The color of transparent box will turn red to indicate that:

And, you can click magnifier buttons in floating toolbox to zoom in/out.

Relocation

At floating toolbox, click icon to reveal relocation options:

The first is a drop-down menu containing list of chromosome names (not including unassembled contigs). If you select a chromosome, the browser will display that entire chromosome. So this is usually a bit slow to update, especially when there's many tracks on.

The first of the two text fields allow you to enter a genomic coordinate and jump to it. The coordinate has to be in this format: "chr1:123-456", and the three fields can be separated by any combination of space/tab/dash/colon. But the chromosome name is case-sensitive, and in the human genome, you have to use "chrX" but not of "ChrX" or "chrx".

The second text field is for genes, where you enter a gene name and view it. The gene name is case-insensitive.


Another relocation method is using the small chromosome ideogram on top-left corner of browser page (which disappears when displayed region spans multiple chromsomes):

In species where the karyotype data is unavailable (like zebrafish), the chromosome image will be a blank box instead of banding graph:

Press cursor button on such chromosome image, a small transparent box will appear to indicate the position and span of your selected region. Release cursor button, the browser will display data over selected region:

Such function still applies in the case of Gene Set View:
