On September 6, 2017, we will present a webinar on Application Programming Interfaces (APIs) at NCBI.
Whether you’re new to APIs or are already using them, this webinar has something for you. We’ll introduce you to APIs and what they can be used for, then focus on the diverse group of APIs available to access NCBI databases and tools.
Date and time: Wed, Sep 6, 2017 12:00 PM – 12:30 PM EDT
After registering, you will receive a confirmation email with information about attending the webinar. After the live presentation, the webinar will be uploaded to the NCBI YouTube channel.
GenBank release 221.0 (8/13/2017) has 203,180,606 traditional records containing 240,343,378,258 base pairs of sequence data. In addition, there are 499,965,722 WGS records containing 2,242,294,609,510 base pairs of sequence data, 186,777,106 TSA records containing 167,045,663,417 base pairs of sequence data, and 1,628,475 TLS records containing 824,191,338 base pairs of sequence data.
NCBI regularly organizes hackathons throughout the United States, where participants work in teams to apply their data science experience with public datasets. In this NCBI Minute, you will hear highlights from recent hackathons, see examples of the software created in these events, and learn how you can participate in future hackathons.
Date and time: Wednesday, August 30, 2017 12:00 PM – 12:30 PM EDT
Do you have trouble searching the NCBI webpage for relevant datasets? Wish you could filter the search results more precisely? You can with SRA Run Selector.
In this NCBI Minute, you’ll learn how to filter the SRA database using the metadata details captured for each submitted dataset. This is easily done in a spreadsheet format that displays all recorded metadata for each SRA Run. The user-friendly interface allows you to selectively filter datasets down to the most relevant data for your research question and then export it in a spreadsheet.
Date and time: Wednesday, August 23, 2017 12:00 PM – 12:30 PM EDT
NCBI will discontinue both the NCBI Genomes (chromosome) and the Human ALU repeat elements (alu_repeats) BLAST databases in October 2017.
Better alternatives to NCBI Genomes (chromosome)
The existing NCBI Genomes (chromosome) database does not offer complete and non-redundant coverage of genome data. The newly added NCBI RefSeq Genomes Database (refseq_genomes) and the RefSeq Representative Genomes Database (refseq_representative_genomes) are more useful alternatives to the chromosome database. You can select these databases from the database pull-down list on any general BLAST form that searches a nucleotide database (blastn, tblastn).
