Assessment of FlyBase euchromatic protein-coding gene annotations

Regions evaluated	Total	Confirm	Abstain	Reject*
Named genes	4,711	4,566 (96.9%)	105 (2.2%)	40 (0.8%)
CGid-only genes	9,022	7,879 (87.3%)	729 (8.1%)	414 (4.6%)
Non-coding regions†	15,564	3 (0.0%)	131 (0.8%)	15,430 (99.1%)

^*A minority of rejected genes are false rejections; see Fig. 3b and text for details.

^†Regions ≥300 nucleotides in length randomly chosen from the non-coding part of the genome (see Supplementary Methods 2a).
