PlantGDB's Comprehensive plant Gene Annotation Tool (CpGAT) workflow allows users to annotate any genomic region using any combination of transcript and protein datasets. The pipeline uses EVM (EVidence Modeler) to evaluate transcript- and ab initio-derived exons, and incorporates PASA to derive UTR regions and alternative splice variants. The pipeline outputs a GFF3-formatted file of gene structures.
