Introduction to the Stop Codon Map

The Stop Codon Map plots the positions of all the stop codons on one or both strands of a contig consensus sequence. If the Contig Editor is being used on the same contig, the Refresh button will be enabled, and if used, will fetch the current consensus from the editor, repeat the search and replot the stop codons.

The figure shows a typical zoomed in view of the Stop Codon Map display. The positions for the stop codons in each reading frame (here all six frames are shown) are displayed in horizontal strips. Along the top are buttons for zooming, the crosshair toggle, a refresh button and two boxes for showing the crosshair position. The left box shows the current position and the right-hand box the separation of the last two stop codons selected by the user. Below the display of stop codons is a ruler and a horizontal scrollbar. The information line is showing the data for the last stop codon the user has touched with the cursor. Also shown on the left is the View menu which is used to select the reading frames to display (see section Stop Codon Map).
