Repeats are shown below the genes, colored. This track contains db. SNP, available. from ftp. On a large region the darkness of a SNP mark corresponds to. SNPs density on this region.
SNPs are also indicated on. Regions of high conservation are colored according to the annotation as exons (dark blue), UTRs (light blue) or non- coding (pink) (Fig. The names of these contigs can be seen on the information panel by hovering the mouse cursor over the graph.

Gumby has no window- size parameter, and no fixed. Since the algorithm uses a more- conserved- than. An extreme example: since. In general, statistical power. Smaller alignments. Gumby detects an inadequate number of aligned.
For the p- values to be meaningful, Gumby requires a reasonably complete. Rule of thumb: the number of . The relative ranking of. However, the p- value estimates would be systematically biased. Gumby's sensitivity in detecting non- exonic conservation can be.
The annotated regions are. Consequently, an unannotated. In another deviation from the standard scheme, Rank. VISTA colors. UTRs and coding exons the same, since they are treated identically by Gumby. Rubin. Olivier Couronne, Len A. Close sequence comparisons are.

The browser will go directly to the location of the gene if there is only one exact match, or display a dialog box if there are more than one. Please note that the browser does have an upper limit on the size of the region it can display at a time.
Position displays the exact base genome coordinate, and Contig shows the name of the corresponding contig on the mapped data set. In addition to navigating the browser by entering exact coordinates in the position control panel and searching by gene names, the browser provides all the standard scrolling and zooming functions.

The first time you do this. Fig. If you have pop- up blocking software (external, such as the google toolbar, or built- in, in IE 6 for example), you will need to disable it - - this is usually done by holding down the CTRL key while clicking the button. Each alignment that forms a given graph will be shown here, including the overlapped ones. You can get the alignments by clicking the appropriate links in the right- hand column. To get annotation for a given segment on the genome, click one of the curves to select it, then click the .
To retrieve the sequences that were aligned to produce the curves you observe, click one of the curves to select it, then click the . To get transcription factor binding site predictions for a given alignment, click one of the curves to select it, then click the . Each alignment that forms a given graph will be shown here, including the overlapped ones. To submit the alignment to r. VISTA, click on the . Note that r. VISTA only takes one pairwise alignment as input, so if the region you are interested in is covered by several alignments, each one will need to be submitted separately.
When another browser is available for the base genome, clicking the . As usual, hold down the CTRL key when clicking on the button if you have a pop- up blocker. When looking at an alignment of two organisms, it is sometimes useful to be able to change which organism is being used as the base. A variable sized window (Calc Window) is slid across the alignment and a score is calculated at each base in the coordinate sequence.
That is, if the Calc Window is 1. X is the percentage of exact matches between the two alignments in a 1. X. Due to resolution constraints when visualizing large alignments, it is often necessary to condense information about a hundred or more base- pairs into one display pixel. This is done by only graphing the maximal score of all the base pairs covered by that pixel. The user can examine the contigs in the overlap individually by clicking the . Conserved regions are defined as regions with conservation score of . Regions that satisfy this constraint are painted according to the annotation; all unannotated regions are painted as conserved non- coding regions (CNS).
Usually this happens when a pop- up blocking software (external, such as the google toolbar, or built- in, in IE 6 for example) is enabled. If you are so inclined, however, you can change the Opera configuration files to grant applets printing priviliges and never have to worry about this issue again: Exit Opera Browser.
