The Heidelberg Collection R1. The combination of the BDGP cDNA Collection (BDGC) R1 with the BDGP genome annotation Release 2 contained 13,861 genes. The Heidelberg Prediction based on the Fgenesh ab initio gene prediction software contains 20,622 predictions. Assuming that genes that overlap by more than 30% of their exon sequence represent the same gene, we combined these two annotation sets. In addition we included 71 genes from different databases that were not present in either annotation. The resulting Heidelberg Collection consists of 21,396 potential genes and is the basis for the Heidelberg FlyArray.
