Sequence View Markers
Step 1: Introduction
This tutorial was prepared using Genome Workbench version 2.7.0
It will take you through the steps of setting and manipulating new markers, showing marker information, changing marker properties, saving and deleting markers.
Step 2: Launch Genome Workbench
Launch the Genome Workbench. You will be presented with the initial screen shown below.
Step 3: Import the test GenBank accession
Click on File drop-down menu and select the Open menu item (or just click on the Open icon in the toolbar) to bring up the Open dialog.
Select Data from GenBank on the left side of the dialog.
Type in "NG_000007" in the entry box on the right side.
Click Next and then Finish to finish loading.
The system will display the new project in the project tree view.
Step 4: Open Graphical View on the imported molecule
Right click on the project item called "NG_000007" in the Project Tree View.
Select Open New View… from the popup menu.
Select ‘Graphical View’ in the next dialog.
A Graphical View should be opened.
Step 5: Set new markers
Zoom the view into the [27,000-29,700] range.
Place the mouse over the ruler bar on the top of the view.
Right click to bring up the context menu.
Select Add New Marker To Position menu item.
Change the marker name to "Marker1"and marker position to "28,000".
Note that marker color is selected randomly. It can be changed now or later if desired.
Click OK to add a new marker.
Repeat the steps above to add the second marker using marker name "Marker2" and marker position "28,400".
Final view after adding two markers: Marker1 and Marker2:
Step 6: Show marker information
Place the mouse over the head portion of any marker.
Right click to bring up context menu.
Click on Marker Details… menu item
The marker information dialog (as shown below) will be displayed. For each marker it shows a list of locations across the marker position for the related sequences, such as NG sequences, mRNAs, and Proteins. It also shows the corresponding HGVS coordinates and the franking sequence around the marker position. Information about HGVS nomenclature can be found here: http://www.hgvs.org/mutnomen/
The marker information dialog is a non-modal dialog. That means a user can manipulate the view while leaving the dialog open. The dialog will always stay on top of other views. For example, while the marker dialog is open, zooming or panning the graphical view is allowed. In addition, changing/adding/deleting markers inside the graphical view will automatically update the marker info shown in the dialog.
Step 7: Change marker properties
Change marker position by clicking and dragging
Place the mouse over the head portion of any marker.
Press down left mouse button and drag the marker.
After releasing the button, the marker information will be updated if marker info dialog is opened.
Change marker name/position/color through marker context menu
Rename Marker… menu item allows changing marker name.
Modify Marker Name/Position/Color… menu item allows changing marker name, position, and color all at once.
Step 8: Delete markers
Markers may be removed from both the marker info dialog or marker context menu individually or all at once. Removing markers from one place (either view or info dialog) will update the other.
Step 9: Save markers
All added markers will be saved to the corresponding Genome Workbench project when the view is closed. Hence, if the same molecule is reopened from the same project, all the previously viewed markers will be added to the view. However, to save the marker permanently, one needs to save the corresponding Genome Workbench projects or the whole workspace when exiting Genome Workbench.
