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.
