Feature exploration
- Finding one or more features by their name or annotation
- Defining a range of interest by position
- Defining a range of interest with the mouse
- The feature/results table
Finding one or more features by their name:
Click on the "Search Feature Table" button
on the toolbar. A table with all features in the dataset will be displayed at the bottom of the window (see
table section below). Enter a feature name or annotation search term and the features
that don't match will be filtered out of the table as you type. You can also enter just a part of a feature name or
annotation term -- wildcard characters are not required. This search is case-sensitive.
Defining a range of interest by position:
Click on the "Explore Range" button
on the toolbar. A dialog will appear where you can specify a genome, chromosome and start/end positions for a range
you want to explore. Click the “Find” button in the dialog and a results table will appear at the bottom of the
window (see
table section below).
Defining a range of interest with the mouse:
A region for displaying all features can also be defined through the view itself. Hold down the Ctrl and Shift keys together (Mac: Shift + Cmd), then click and drag next to a chromosome along the region of interest. This will draw a selection rectangle. Selecting a region with the mouse will also highlight all the homologies originating in this region in real time. Right-click and choose "Show annotation for features in range" from the context menu. This will display the results table (see table section below).
Press the ESC key to undo the selection and start over again.
Back to topThe feature/results table:
The table at the bottom of the Strudel canvas either displays the full set of features in the currently loaded dataset or a subset thereof, depending on how it was invoked (see above).
Click one or more (Ctrl-click) rows in the table to display the features on the canvas. The results in the list can be filtered by genome by using the drop-down menu in the results table’s control panel at the bottom left. One can also click the checkboxes to display labels and links for features if a range was specified either through the dialog or with the mouse. Sort the table by clicking on one header at a time.
Clicking on the feature name hyperlinks will bring up a web browser with annotation information if a target URL for the genome in question was specified in the data file. The feature name is appended to the URL and a web browser will open with the corresponding page loaded.
Results tables can be saved to a tab delimited text file by clicking the save
button on the toolbar, which opens a file save dialog.
