The descriptions of the features associated with genomic islands

Feature	Description
IVOM	Interpolated Variable Order Motif compositional score (Relative Entropy)
Insertion Point (IP)	Binary: “1” if within a CDS locus, “0” otherwise
Size	Size of each genomic region in bp
Density	Number of genes per kb
Repeats	Binary: “1” if repeats present, “0” otherwise
Integrase	Binary: “1” if containing integrase-like protein domain, “0” otherwise
Phage	Binary: “1” if containing phage-related protein domain, “0” otherwise
RNA	Binary: “1” if containing non-coding RNA, “0” otherwise
