Check whether (the 3' ends of) E. coli ORFs cross-hyb anywhere in the genome.

genes to check		Specify gene names and/or Blattner numbers, one per line (case-sensitive). Optionally, to check less than the entire ORF, append the 3' fragment length to individual genes, or specify a single value below. Separate gene and fragment length by a space or tab.
3'-end fragment length to check		Leave blank for entire ORF. Used for all ORFs except if specified above for individual ORFs. If this value exceeds the length of an ORF, the entire ORF is used.
