May 16 webinar: Improved Standalone BLAST database and programs: now with taxonomic information


Next Wednesday, May 16, 2018, we’ll show you how to download and use the latest standalone BLAST databases, dbv5. You’ll learn how to use BLASTdbv5 and the new BLAST programs to limit searches to taxonomic groups and to retrieve sequences from the database by taxonomy.

Date and time: Wed, May 16, 2018 12:00 PM – 12:30 PM EDT

May 9 NCBI Minute: Integrating PubChem into Your Chemistry Teaching


Next Wednesday, May 9, 2018, NCBI staff will show you how to use PubChem as a cheminformatics education resource. In addition to learning about tools and services for chemical information search, analysis, and download, you will also see examples of how instructors incorporate PubChem in Cheminformatics OLCC (On-Line Chemistry Courses), an intercollegiate hybrid course.

The NCBI BioCollections database links specimen vouchers and sequence records to home institutions


A paper in the January 2018 issue of Database describes the NCBI BioCollections database, a curated dataset of metadata for culture collections, museums, herbaria and other natural history collections connected to sequence records in GenBank. The BioCollections database was established to allow the association of specimen vouchers and related sequence records to their home institutions. This process also allows back-linking from the home institution for quick identification of all records originating from each collection.

The rapidly growing set of GenBank submissions frequently includes records that are derived from specimen vouchers.  Correct identification of the specimens studied, along with a method to associate the sample with its institution, is critical to the outcome of related studies and analyses.

New repository records are added to the database if they are submitted to the International Nucleotide Sequence Database Collaboration (INSDC) along with sequence data. Each record now provides information about the institution that houses the collection, standard Institution Code, mailing address, and associated webpage if available.

The BioCollections database is maintained and curated by the Taxonomy group at NCBI.
