GenBank release 235.0 (12/11/2019) is now available on the NCBI FTP site. This release has 7 trillion bases and 1.74 billion records.
The current release has 215,333,020 traditional records containing 388,417,258,009 base pairs of sequence data. There are also 1,127,023,870 WGS records containing 6,277,551,200,690 base pairs of sequence data, 367,193,844 bulk-oriented TSA records containing 325,433,016,129 base pairs of sequence data, and 28,227,180 bulk-oriented TLS records containing 11,280,596,614 base pairs of sequence data.
GenBank submitters, you can now submit mitochondrial COX1 (cytochrome oxidase subunit I; COI) sequence data from multicellular animals (metazoa) using a new workflow (Figure 1) with an improved interface, enhanced validation, and automatic COX1 CDS feature annotation. Once you have submitted mitochondrial COX1 data using this tool, you’ll have a single, helpful page to reference your submission information: accession number(s), COX1 submission status, relevant files and more. Plus, you can also fix any errors from this page.

Do you need a quick way to annotate features on a similar set of sequences for your GenBank submission? You can now submit sequences from the same region or gene in an alignment format in BankIt and use the new ‘Feature propagation option’ (Figure 1) to apply features from a single sequence to other aligned sequences. You simply annotate one sequence and then copy that annotation across all the sequences in your submission.
Here’s how you can propagate features in three easy steps:
A new version of the Prokaryotic Genome Annotation Pipeline (PGAP) is now available on GitHub. This release uses a new and improved version of tRNAscan (tRNAscan-SE:2.0.4) and includes our most up-to-date Hidden Markov Model and BlastRule collections for naming proteins.
Remember that you can submit the results of PGAP to GenBank. Or, if you are still improving the assembly and your genome doesn’t pass the pre-annotation validation, you can use the –ignore-all-errors mode to get a preliminary annotation.
GenBank release 234.0 (10/14/2019) is now available on the NCBI FTP site. This release has 6.69 trillion bases and 1.68 billion records.
The release has 216,763,706 traditional records containing 386,197,018,538 base pairs of sequence data. There are also 1,097,629,174 WGS records containing 5,985,250,251,028 base pairs of sequence data, 342,811,151 bulk-oriented TSA records containing 305,371,891,408 base pairs of sequence data, and 27,460,978 bulk-oriented TLS records containing 10,848,455,369 base pairs of sequence data.
Validation issues can delay the processing of your submissions to GenBank. To avoid one type of delay, use the new “expected genome size” API to check the length of your genome assembly before submission.
The API compares the size of submitted genome assemblies to the expected genome size range for the species to identify outliers that can result from errors such as:
incorrect organism assignment
metagenome submitted as an organism genome
targeted sub-genome assembly not flagged as partial genome representation
gross contamination with other sequences
You can check in advance for these possible problems using the API. The API accepts the taxid for the species (taxid = Taxonomy ID – see our Taxonomy quick start guide on how to find the taxid for a given species) and the length of your assembly (excluding gaps and runs of Ns) as input and returns XML with the expected length, the acceptable range, and a status that tells you whether your assembly is too large, too small, or within the acceptable range. Look for <length_status>within_range</length_status> which confirms that your sequence passes the test!
We have released a new version of the Prokaryotic Genome Annotation Pipeline (PGAP), available on GitHub. The new release includes the ability to ignore pre-annotation validation errors (–ignore-all-errors). This new feature allows you to produce a preliminary annotation for a draft version of the genome, even one that contains vector and adapter sequences or that is outside of the size range for the species. This draft annotation should be helpful with your ongoing work on the genome assembly. Please keep in mind that these pre-annotations and assemblies with contaminants or other errors are not suitable for submission to GenBank.
Another new feature allows you to provide the name of the consortium that generated the assembly and annotation so that this information appears in the final GenBank records. For more details, consult our guidelines on input files.
See our previous post and our documentation for details on how to obtain and run PGAP yourself.
Next on our to-do list is a module for calculating Average Nucleotide Identity (ANI) to confirm the assembly’s taxonomic assignment. Stay tuned!
