The following table lists ways in which you can customize the appearance and layout of views.
Task | How to… |
---|---|
Show a view | Use View > (View Name) > Show. |
Change the style (fonts, colors, calculation metrics and more) | Use the Style panel and its subsections. Customization for font style and size applies to all text in a view. Individual rows cannot have different styles. |
Move one or more sequence rows as a group | Sequence rows in some views may be rearranged one at a time or as contiguous groups using drag and drop. First, select the desired rows using Ctrl/Cmd+click or Shift+click. Next, drag the selected row(s) to the desired location and release the mouse button. Any ordering changes made to one view are simultaneously made to the other. |
Detach a view | Only certain views can be detached. To do this, right-click on the view tab and choose Detach (View Name). Detaching a view turns it into a free-floating window. Note that each detached view has menus in the upper left corner. For example, if you detach a Tree view and then wish to use commands such as Tree > Root On, you must use the menu in the detached view rather than the menu in the main MegAlign Pro window. |
Reattach all detached views to their original locations | Use View > Reattach All Views. |
Show the active view in full-screen mode | Use the View > Full Screen command or the Full screen tool |
Exit from full-screen mode | Click the Esc key, use the Exit Full Screen tool ( |
Configure the number and location of visible views. | Use the View > Document Layout command or the Change layout tool (image varies) in the bottom right corner of the view to access possible layouts. The following options are available:
|
Zoom in or out on a view | Some views have independent vertical and horizontal zoom in/out sliders. Grab any green slider with your mouse and drag left/right or up/down to zoom in or out in the view. For details, see the table just below this one. |
Split a view vertically | Use Overview > Split View or Analysis > Split View. The split can be moved by dragging it left or right with the mouse. Alternatively, you can drag the vertical splitter tool ( When the Analysis view is split vertically, the Overview provides a separate viewport indicator for each section. Splits are ignored when printing or exporting an image, although the layout is preserved. |
Remove the right-most vertical split | Use Overview > Remove Split or Analysis > Remove Split. Or drag the divider as far as you can to the side of the view and drop it there. |
To view two or more documents simultaneously on a split screen | By default, only one document at a time is displayed, even if several documents are open. To view two or more documents simultaneously on a split screen, drag a project tab in a downward, right or left direction. When you see a black arrow, release the mouse button. Documents can be re-docked in their original positions by reversing this process. |
Return to the default window display | Choose View > Reset Panel Layout. |
Three of MegAlign Pro’s views (Sequences, Tree and Overview) all have independent vertical and horizontal zoom in/out sliders. The following table uses the Sequences view as an example to show the look of the sequences and some of the detail tracks at different zoom levels.
Track | Maximum Zoom | Medium Zoom | Minimum Zoom |
---|---|---|---|
Sequences | |
Once the letters disappear, only the background color, if any, is shown. |
At minimal zoom levels, sequences are shown as colored bars with white gaps. |
Sequence Logo | |
Once the logo letters disappear, only the background color, if any, is shown. |
Some tracks cannot be displayed at low zoom levels, and prompt you to zoom in. |
Consensus Match | |
