This page provides help for the Splicing Graph Viewer (see methodology for the advantages of splicing graphs.)The screenshot below shows an example of the Splicing Graph Viewer (click here for a larger screenshot). Users first select a splicing graph that they are interested in via the query page or using the navigational aids. The users can then click on specific items in the splicing graph and transcripts to see detailed information in the "Detailed information" region. Alternatively users can opt to view information about the splicing graph by selecting an item from the "Detailed information menu".
There are 5 regions highlighted in yellow in the screenshot. Click on them for more information about that region.
A close up of the navigational aids is shown below (click for a larger image). The button labeled "DEDB" brings the user back to the query page allowing the user to query the database using various methods. The next and previous buttons provide a means to browse the splicing graphs back and forth. The "Next AS" and "Previous AS" buttons allow users to jump to the next and previous alternative splicing graph quickly. Users can also use the selector to navigate to specific types of alternative splicing graphs by selecting a specific alternative splicing type and then clicking the "Go" button.
A close up of a splicing graph is shown below. Each of the black colored bars represent a node. Users can click the node to see detailed information on the node in the "Detailed Information" region. The green colored lines represents connections which linked nodes together. The Node ID is displayed in white numbers within the black bars. The start and stop codons are represented by green and red colored lines respectively within the nodes.
A close up of the transcript region is shown below. Each transcript that makes up the splicing graph is shown in this region. Each of the transcript is represented by a series of black colored bars representing the exons that are connected by introns represented by green lines. Both the exons and introns can be clicked to reveal more information in the "Detailed Information" region. On the top left of each transcript is the transcript name. In the middle of the intron is a number representing the intron phase. The start and stop codons like the splicing graph are represented by green and red lines respectively. The Pfam domains mapped onto the exons are displayed as colored bars below the transcript. Each Pfam domain can occur more than once in the transcript and this is reflected by the fact that these domains share the same color. Similar to the exons and introns, more information can be obtained by clicking on the domain.
The detailed information menu provides a means to display specific information concerning the splicing graph. The information will be displayed just below the menu in the "Detailed Information" region. The details of each button is provided below:
This region provides space for detailed information about selected items. For items with sequence information, a "Download FASTA sequence" button will appear. Click on this button to open a new page with the FASTA sequence of the item in question.
