Workspace and Viewing Preferences


The Dashboard is the first thing you see when you log in. It is where you start creating sequence from (click on “New Vector”). The Dashboard’s organization Is very simple: you see the list of vectors (sequences). For each file, the creation date and last modification date are displayed, and to delete sequence, click on ⋮. Clicking on the User icon gives an option to log out. The total number of sequences is displayed in the bottom.

The Contents and Panels of the Workspace

Your workspace contains the main Control Panel on the top, an additional Feature Panel on the bottom, two view modes for your sequence on the left, and sequence itself/properties on the right. To learn more about extensive features within the Control Panel, read here. 

The bottom panel allows you to make the following changes to how you see the sequence (no bases selected):

  • Editable/Read-only
  • Circular/Linear
  • Available/Unavailable
  • Position of Caret (will be displayed as “Caret Between Bases … and …”)
  • Select Inverse (selects all bases of the vector)
  • Length of the vector (in bps)

Once you select the bases, there are some changes: you will see the number of base pairs selected, positions of the first and last base pair selected, GC content (in %), and Tm.

Once you click “Select Inverse”, the rest of the vector will be selected, except for the region you picked.

You can select what algorithm has been used for calculating the Tm of the sequence. Click on the bottom panel’s Tm value (See Thermodynamic Settings for details).

Sequence and Vector View

You can select how you view your vector: either as a Circular Map or Linear Map. This view is display only (it is not possible to make nucleotide changes directly on it – only on Sequence Map) and it helps navigate within your vector and see it more broadly. To navigate to the location/feature on the Circular or Linear Map, click on it, and the caret will jump to the location on the Sequence Map. Sequence Map contains an editable sequence, where you will perform your editing. As you reach the end of your sequence, there is a button that returns you to the beginning (first base) of the sequence.

The Properties window shows the summary of your sequence metrics: all features, parts, primers, translations, cut sites, ORFs. Additionally, it provides GenBank entry for your sequence. You can edit the Name of the sequence and write up a short description in the Properties window as well.

Zooming in Function

Zooming Map is also available. To access it, select “Open Zoomable View” in “View”:

The Zooming Map allows you to navigate the plasmid map and zoom into the features/parts.

See below for detailed explanation of the basic functions.

Local Zoom InZoom In to see the nucleotide level. Zoom Out to see the feature/part level.1. 0%
2. ~50%
3. ~80%
Global NavigationThe axis corresponds to each nucleotide position in the sequence. Slide left/right to move along the vector. The slider can be extended (Picture 2) to capture larger part of the sequence.1.
