GQuery: NCBI Global Cross-database Search

The major advantage gqueey GQuery is the common interface to the different databases: You can also search Genbank through their search portal, GQuery, formerly known as Entrez. Gqusry databases National Institutes of Health Biological databases Government-owned websites Gquery search services. In other projects Wikimedia Commons. But more importantly, it allows very finetuned searching ncbi the annotations of sequences. This filter selects only primary records from Genbank so no RefSeq records will be present in the results summary. The disadvantage is that by linking all these resources together, you can get lost in GQuery You already know the look of the results page from the Genbank searches. The name "Entrez" a greeting meaning "Come in! Type the search term hiv in the box and click Search. From Wikipedia, the free encyclopedia. So in the GQuery search term box type the following query: Users with a MyNCBI account can save queries indefinitely and also choose to have updates with new search results e-mailed for saved queries of most databases. Search results can be saved temporarily in a Clipboard. GQuery is the name of the search portal that searches in all NCBI databases non-sequence databases will be covered ncbi into more detail.

Look in the Ncbi details box how this filter is translated in the actual query that is used to search the database:. Activate the Sequence length filter and set the range to to It seems very strange that the Genomic Survey Sequence database contains mRNA sequences since by defintion it is supposed to include only genomic sequences. On the GQuery page you see a list of all the databases that are searched by GQuery, grouped according to topic. This returns a unified results page, ncbi gquery, that shows the number of hits for the search in each of the databases, which are also links to actual search results for that particular database. The search bar you find at the top, is the GQuery search tool. The GQuery results page returns the same list of NCBI databases, together with the number of records found in each database containing the word hiv. Remove all filters set in the previous exercise Do an advanced search: Now check the results gquery the Nucleotide database. Not only searches are similar but also the result pages of all NCBI databases look the same in Entrez. In the Nucleotide database it's a sequence length in base pairsin the Protein database it's a sequence length in amino acids. Entrez can efficiently retrieve related sequencesstructuresand references. For instance, click Nucleotide to see the results from Genbank's nucleotide database. Entrez Global Query is an integrated ncbi and retrieval system that provides access to all databases simultaneously with a single query string and user interface.
