The 2018 Nucleic Acids Research database issue features several papers from NCBI staff that cover the status and future of databases including CCDS, ClinVar, GenBank and RefSeq. These papers are also available on PubMed. To read an article, click on the PMID number listed below.
Submitting sequences to GenBank can seem complicated at first, but starting with a solid foundation in the form of a properly formatted file will make the process go smoothly.
Before submitting sequence data to GenBank, the data must be formatted correctly, the most common file format being FASTA. This post will show you how to create a FASTA file for submitting single- and multiple-nucleotide sequences.
Submitters can upload FASTA-formatted sequence files using NCBI’s stand-alone software Sequin, command line tbl2asn or our web-based submission tool BankIt.
The image below depicts a single sequence in FASTA format. For multiple sequences, such as those of population or phylogenetic studies, environmental samples, and batch sequences of the same gene, create the file using the steps below and put the set of sequences together in a single FASTA file.
Here is how to create the FASTA file:
