                                The Genome Browser's codon coloring feature allows
			 	users to quickly validate and compare gene 
				predictions and annotations. To turn on codon coloring, select the
				genomic codons option from the Color 
				track by codons pull-down menu. 
                                  
				Color Legend
 
				bright green codons/lines: methionine, including start 
				codonscyan text: partial codon, either 
				spliced or truncatedred "*": stop codonsblack "X": error (e.g. truncated last codon) 
				All other codons are shown in the original track color, 
				with codon boundaries indicated by alternating lighter 
				and darker shades.
				 
				DetailsEach codon is colored and labeled in the direction of 
				transcription. This coloring applies only to gene prediction and 
				annotation tracks; thus the codon sequence is colored
			        in reference to the genome and not the associated mRNA.
				A gene prediction without a CDS will not be colored; these 
				can be non-protein-coding RNAs or predictions where a 
				CDS annotation was not provided in the original data.
 	
                                To view codon coloring, the option must be
				turned on, the track must be in squish, pack, or
				full display mode, and the browser must be 
				zoomed-in to a level at which there is at least 
				one pixel per codon. When zoomed out to large 
				regions of the genome, the browser will not display
			        codon coloring. To view labeling, the
                                track must be zoomed to within 3 times
	                        the base level. |
