[i] Statistics are as of June 4, 1999. The references from which load files were obtained comprise those cited in Table 1 plus two others (Eisen et al. 1998; Marton et al. 1998). Several of these were recorded under multiple Expression Data Set records. ORF records comprise more than actual yeast ORFs but also represent control features for which data is reported by RNA collection methods as well as some non-ORF entities loaded with ORF Group and Saccharomyces Genome Database (SGD) information (Cherry et al. 1999).
