Microbial Genomes Curator @ Computercraft Corporation--Maryland (US).  Submitted by Computercraft Corporation; posted on Saturday, March 17, 2012 RESPONSIBILITIES: Computercraft seeks a microbiologist to work with a team of software developers and biologists on microbial genome analysis including pan-genome, protein clusters, phylogenetic tree and more. This is a technically challenging position requiring experience in genome sequencing and annotation. A background in comparative genome analysis such as alignments and tree building is a plus. Our scientists work with genomic experts at the NIH's National Center for Biotechnology Information (NCBI) to create and enhance a suite of databases and tools available to researchers worldwide. Teamwork interaction and excellent organizational skills are essential for this detail-oriented position, as is scientific problem-solving with a results-oriented focus. REQUIREMENTS: * PhD in molecular biology, microbiology, or related field * ...

"There does appear to be a distinction between the way curation is used in the bio-sciences, and elsewhere. In particular, the term "curated database" tends to mean a manually constructed database that links literature to data, curated by experts who provide authority (eg see the Wikipedia definition of Biocurator ). The earliest mention of the term "curated database" I can find is in the abstract (and only in the abstract) of Larsen et al (1993)." Chris Rusbridge Digital Curation Blog Since these database are hand curated by experts (manually curated), they always promise a accuracy & quality better than uncurated or NLP based databases. While NLP based databases follow a automated curation provide quick updates and tend to be large in terms of the quantum of data. While they may trade off in accuracy due to their automated curation process. While platforms like XTractor Premium follow a unique approach by trying to adopt the best of both worlds. A ...

Among number of challenges faced by informatics one of the long standing and critical challenge has been the Biodiversity informatics: the challenge of linking data and the role of shared identifiers . A major challenge facing biodiversity informatics is integrating data stored in widely distributed databases . Initial efforts have relied on taxonomic names as the shared identifier linking records in different databases. However, taxonomic names have limitations as identifiers, being neither stable nor globally unique, and the pace of molecular taxonomic and phylogenetic research means that a lot of information in public sequence databases is not linked to formal taxonomic names. This review explores the use of other identifiers, such as specimen codes and GenBank accession numbers, to link otherwise disconnected facts in different databases. The structure of these links can also be exploited using the PageRank algorithm to rank the results of searches on biodiversity datab...

The Protein Data Bank Japan (PDBj) curates , edits and distributes protein structural data as a member of the worldwide Protein Data Bank (wwPDB) and currently processes 25–30% of all deposited data in the world. Structural information is enhanced by the addition of biological and biochemical functional data as well as experimental details extracted from the literature and other databases. Several applications have been developed at PDBj for structural biology and biomedical studies : (i) a Java-based molecular graphics viewer, j V; (ii) display of electron density maps for the evaluation of structure quality; (iii) an extensive database of molecular surfaces for functional sites, e F-site, as well as a search service for similar molecular surfaces, e F-seek; (iv) identification of sequence and structural neighbors; (v) a graphical user interface to all known protein folds with links to the above applications, Protein Globe. Recent examples are shown that highlight the...

The Single Nucleotide Polymorphisms database (dbSNP) serves as a central repository for both single base nucleotide substitutions and short deletion and insertion polymorphisms. Computercraft seeks a biologist with significant knowledge in life sciences to help curate dbSNP records, process submission, and perform data analyst tasks. Candidates should also have the ability to rapidly develop applications to process data into database and to generate reports. The individual will work onsite at the National Institutes of Health (NIH) in Bethesda, MD. Our scientists work with genomic experts at NIH's National Center for Biotechnology Information (NCBI) in the National Library of Medicine (NLM) to create and enhance a suite of databases and tools available to researchers worldwide . Requirements: • PhD or M.S. in molecular biology, bioinformatics, or highly related field • Linux/UNIX experience • Relational database and SQL experience • Programming experience (Perl, Python, or C++) •...

" Work created before the existence of copyright and patent laws also form part of the public domain . The Bible and the inventions of Archimedes are in the public domain. However, copyright may exist in translations or new formulations of this work. " [ Wikipedia ] As posted by Tony is the Chemical Abstract Service (CAS) discouraging using their CAS services for assigning correct CAS numbers to structures for any third party database. Wikipedia is a source of structures, which is public domain due to its GNU FDL . Still, this does not imply that any translation of structures, e.g. CAS numbers, are in the public domain, too. Honestly, this raises a serious problem for curating CAS numbers on Wikipedia and this raises indeed the question, if they should not be dropped from Wikipedia, and any other information source, at all? Is it not better having no information, than having wrong information? A CAS number is for me only one certain translation of a chemical structure....
