We’ve had quite a few users calling up recently to ask how to get the arrows representing a feature in the Map view to point “the other way”. The arrows in the Map view are always shown pointing in the 5′ to 3′ direction relative to the feature, i.e. left to right for a feature on the plus strand. If you want the arrow to point “backwards”, all you have to do is tell MacVector that the feature is on the minus, or “complementary” strand. This is easy to do and is outlined in the graphic below.
Select the feature that you want to have the arrow point the other way. Click on the Edit button on the toolbar to open the editor for the GenBank representation of the sequence. Now select the Complementary checkbox and click OK. The arrow representing the feature will now point in the opposite direction.
