First Offering of NCBI NOW (Next Generation Sequencing Online Workshop) Begins October 13!

NCBI will present the first iteration of NCBI NOW, a free online experience aimed at those new to next generation sequencing (NGS) analysis, from October 13-23. Enrollment in this course is limited to the first 1,000 participants who sign up through the ORAU Portal. Since enrollment is on a first-come, first-served basis, please only sign up for this educational opportunity if you will be able to participate fully. Learners will watch 6-7 videos (average video duration: 45-60 minutes) online during the first seven days of the course. These videos will cover the basics of NGS data, preprocessing, quality control and alignment strategies for both DNA-Seq and RNA-Seq, as well as a brief discussion of downstream analysis. Additionally, there will be demonstrations about leveraging BLAST tools for NGS analysis.

Next, participants will apply a selection of RNA-Seq alignment algorithms over three days (1-2 hours per day), mapping RNA-Seq data to GRCh38 chromosome 20. Finally, participants will compare the results of these mappers for specific genes. Throughout the course, participants will be able to post questions at Biostars; experts from NCBI and elsewhere will be available online to answer questions. Learners will emerge from the course equipped to map their own RNA-Seq or DNA-Seq data to the human genome, understand the options for downstream analysis, and use their understanding of the basic steps of data processing to interact more effectively with bioinformatician collaborators.

NCBI Homepage Update: Action Buttons and Category Pages

The NCBI homepage has six new buttons on it: Submit, Download, Learn, Develop, Analyze, and Research. Each of these leads to an action page devoted to a particular set of services. These action pages allow easy access to the pages and resources you need to complete tasks. For instance, you can: Find information about the Entrez API; Find an upcoming NCBI webinar, Find an NCBI tool that designs PCR primers, and much more! On the new action pages, you’ll also see six categories in the header: Literature, Health, Genomes, Genes, Proteins, and Chemicals. These category pages highlight useful databases, tools and resources for each of the topics all in one place.

Also included is a blue Feedback button on the left side of the Download, Learn, Develop, and Analyze pages so that you can send comments to NCBI. More information about the new homepage will be released on NCBI News and to the blog, NCBI Insights.

The articles are all available from PubMed.

SciENcv Enhancements: NIH and NSF Biographical Sketch Formats

SciENcv enhancements will include the new NIH biographical sketch format as a choice for creating SciENcv profiles. SciENcv will continue to support the current NIH biographical sketch format; however, NIH encourages researchers to use the new format with their grant submissions. Researchers will be required to employ the new NIH biographical sketch starting May 25, 2015. Users will be able to utilize their existing Science Experts Network Curriculum Vitae (SciENcv) profiles to create profiles in the new NIH biographical sketch format, as well as be able to select the new NIH biographical sketch format when creating profiles manually or through a data feed from an external source. The Personal Statement section of the NIH biographical sketch has been updated to include an option to list up to four peer-reviewed citations. A new section, Contribution to Science, replaces the former section Selected Peer-Reviewed Publications, and it aims to give researchers a place where they can describe five of their most significant contributions to science.

SciENcv users will also soon be able to create profiles in the National Science Foundation (NSF) biographical sketch format. This newly added format will be available to download in PDF, MS Word or XML, and users will be able to share their SciENcv NSF profiles through a public URL. In addition, by linking your NSF account to an NCBI account, you will be able to populate SciENcv profiles with information stored in your NSF account. The NSF biographical sketch is the official format used for grant submissions to the NSF and consists of five sections: Professional Preparation, Appointments, Products, Synergistic Activities, and Collaborators & Other Affiliations.

NCBI HIV-1 Website Updated

The HIV-1, human interaction database has been updated and is now on an improved page. The improved interface includes help documentation and supports structured queries against Gene, as well as browsing, filtering and downloading the protein and replication interaction data sets. The most recent data release (June 2014) includes 12,785 HIV-1, human protein-protein interactions for 3,142 human genes and 1,316 replication interactions for 1,250 human genes. The HIV-1, human interactions project, collates published reports of two types of interactions – HIV-1, human protein interactions, and human gene knock-downs that affect virus replication which are reported as “replication interactions.”

PubChem Turns Ten!

PubChem logoSeptember 16, 2004 is a special day in the history of PubChem. It marks the beginning of PubChem as an on-line resource! Now fast forward ten years. PubChem provides information daily to many tens of thousands of users. Despite the passage of time, PubChem’s primary mission remains the same: providing comprehensive information on the biological activities of chemical substances.

Providing chemical information to researchers in the biomedical science community is a key part of PubChem’s purpose. Over the years, PubChem introduced and incrementally developed several interfaces, each with its own distinct purpose and set of use cases. Primary to these is the Entrez search interface, where PubChem is organized as three distinct databases: Substance, Compound, and BioAssay. Substance provides substance descriptions (accession number: SID), Compound provides the unique small-molecule chemical content of Substance (accession number: CID), and BioAssay provides biological experiment results for substances (accession number: AID). Each of these databases has an advanced search interface and contain numerous indexes and filters, which can be combined to construct elaborate queries. Additional interfaces exist to search and analyze information in PubChem, including the ability to analyze bioactivity information, download chemical and assay data, search by chemical structure or protein sequence, navigate using integrated classifications, visualize chemical 3-D information, and more.

PubChem continues to evolve the way it provides on-line content. External search engines (like Google, Bing, and others) are now a key way in which researchers locate data. In addition, programmatic interfaces now account for a significant portion of PubChem’s overall usage (+50%). Key programmatic interfaces to PubChem include Entrez Utilities and PUG/REST.
