IslandPath Analysis: Escherichia coli str. K12 substr. MG1655



Each circle in the graphic corresponds to a predicted protein-coding ORF in the genome. Circle colours indicate if an ORF has a higher or lower %G+C than cutoffs you set below --(default is +/- 3.48 of the mean %G+C). Strike lines across the circles represent regions with dinucleotide bias above a pre-determined cutoff. Click on a circle to view a different portion of the table presented below the graph (default is the first 100 ORFs).
A yellow circle indicates its %G+C value is bigger than the high value. A green circle indicates its %G+C value is bigger than the low value and smaller than the high value. A pink circle indicates its %G+C value is smaller than the low value. A strike line across the circles indicates the region has dinucleotide bais above 1 STD DEV. A black verticle bar indicates a transfer RNA gene lies between the two ORFs. A purple verticle bar indicates a ribosomal RNA gene lies between the two ORFs. A deep blue verticle bar indicates both a tRNA and rRNA gene lie between the two ORFs. A black square indicates the dot is annotated as a transposase. A black triangle indicates the dot is annotated as an integrase. Low: High: Mean: 51.16 STD DEV: 4.75
