  • a Transfrags cDNA (1 of 2) = A375 and Jurkat cDNA data combined into a nonoverlapping map. + strand (1 of 2) = A375 and Jurkat (+) strand specific data combined into a nonoverlapping map. - strand (1 of 2) = A375 and Jurkat (-) strand specific data combined into a nonoverlapping map.

  • b A set of transfrags that overlap between the cDNA and RNA direct-labeling assays was generated. The resulting set was then compared to the indicated annotations for each chromosome and strand.

  • c Only ESTs of confident strandedness were used, where strandedness evidence comes from splicing and/or having a polyadenylation site, possibly with associated signal.

  • d Percent base-pair coverage in B that is antisense to the annotations.

  • e Distribution of the base-pair coverage of the novel intronic transfrags based on the strand of the overlapping annotation.
