a Categories are as follows: "5' and 3"' indicates contigs matched by reliable and significant (RS) tags in both sense and antisense orientation simultaneously; "5' or 3"' indicates contigs matched in their sense or antisense orientation but not both; "with tag but no match" indicates contigs with in silico identified GATC tag sites but without sequenced signatures (the presence of a DpnII site but no matching MPSS tag, see materials and methods for details); and "without tags" indicates contigs lacking GATC sites.
