[i] Multi-exon and single-exon predictions are subdivided and exhibit significantly different validation rates. Further classification by longest cDNA promoter and alternative (internal) promoter show higher success among longest cDNA predictions within both categories. High Confidence predictions (Hi-Conf) indicate support for a transcription start site either by a RefSeq gene or greater than 1 cDNA within the gene model used for the prediction.
