Errors in the supplied annotation of a set of cDNA clones that were sequenced bidirectionally were identified and corrected to generate accurate counts of EST frequency. Errors are categorized by the scope of the error, from "well slips" between single pairs of 5' and 3' 96-well plates of ESTs, through incorrectly identified pairs of plates of increasing scope. The number of times each error occurred (pairs or larger groups of 96-well plates affected) and was corrected is shown. Errors that are visualized by dot-plot in Figure 1 are cross-referenced.
