====================================================================== Note: The NCBI eukaryotic genome annotation pipeline is now using Annotation Release numbers. To avoid confusion between the independent notions of a genome assembly and its annotation, NCBI is now using Annotation Release numbers to designate annotation versions. Annotation Release numbers: - are integer values that increment each time the genome annotation is updated. - have initial values starting at 100 or higher. - are incremented independently for each organism. This means that different organisms may have the same release number (eg. Homo sapiens Annotation Release 103, Mus musculus Annotation Release 103) but the two annotation runs are not connected. In addition, differences in the release number value for different organisms does not imply anything about how up-to-date the annotation is for that organism (e.g., Mus musculus Annotation Release 102 could be a newer dataset than Homo sapiens Annotation Release 103). - are used for the set of annotations calculated on one or more genome assemblies. For instance, Homo sapiens Annotation Release 103 includes an updated annotation for the reference assembly, the HuRef assembly, and the CRA_TCAGchr7v2 chromosome 7 assembly. Therefore, a specific genome annotation dataset is specified by the combination of two identifiers, the NCBI taxonomy ID or species name and the Annotation Release number. The specific Annotation Release has pointers to the assembly accession.versions that were the substrates for the annotation run. ====================================================================== Release name: NCBI Gorilla gorilla Annotation Release 100 Release date: 5 December 2012 Freeze date for component genomic sequences: 5 May 2011 Freeze date for other genomic sequences: 20 November 2012 Freeze date for mRNAs/ESTs used for annotation: 20 November 2012 Assemblies in NCBI Gorilla gorilla Annotation Release 100: * gorGor3.1 (GCF_000151905.1) Genomic DNA sequence released by The Wellcome Trust Sanger Institute on 5-May-2011 and used as the reference assembly. The full gorGor3.1 assembly is comprised of the following 3 assembly-units: #Assembly-unit id Assembly-unit name GCF_000227165.1 Primary Assembly GCF_000227155.1 cut_fragments GCF_000027375.1 non-nuclear The primary assembly represents the assembled chromosomes, plus any unlocalized or unplaced sequence that represent the non-redundant, haploid assembly. The cut_fragments alternate loci represent regions for which there is variation from the sequence in the primary assembly. The non-nuclear assembly-unit contains the NCBI Reference Sequence (RefSeq) for the gorilla mitochondrion genome. ======================================================================
