This dataset presents the Halyomorpha halys Official Gene Set (OGS) v1.2. OGSv1.2 is an update of Halyomorpha halys OGSv1.1 (https://doi.org/10.15482/USDA.ADC/1504240) to the coordinates of genome assembly GCA_000696795.3 (https://www.ncbi.nlm.nih.gov/assembly/GCA_000696795.3) using https://github.com/NAL-i5K/coordinates_conversion/. The original OGSv1.0 is an integration of automatic gene predictions from NCBI's eukaryotic annotation pipeline, NCBI Halyomorpha halys Annotation Release 100 (https://www.ncbi.nlm.nih.gov/genome/annotation_euk/Halyomorpha_halys/100/; ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/696/795/GCF_000696795.1_Hhal_1.0), with manual annotations by the research community (performed via the Apollo manual curation software, http://genomearchitect.org/). Manual annotations performed by the community were downloaded from Apollo, QC'd, and merged with NCBI Halyomorpha halys Annotation Release 100 using the GFF3toolkit software (https://github.com/NAL-i5K/GFF3toolkit/releases/tag/v1.4.4). The resulting merged dataset was formatted for ingest into the i5k Workspace and GenBank databases, resulting in Halyomorpha halys Official Gene Set (OGS) v1.0. Halyomorpha Official Gene Set halhal_OGSv1.1 is a minor update of halhal_OGSv1.0: Alias attributes were added to all manually annotated cathepsin models; six models from contaminated scaffolds were removed; and notes were added to 3 models located on possibly contaminated scaffolds.
