GQuery: NCBI Global Cross-database Search

On the results page you ncbi that the Protein database returns the highest number of hits. It seems very strange that the Genomic Survey Sequence database contains mRNA sequences since by defintion it is supposed to include only genomic sequences. GQuery reports how many hits it has found in every db. From Wikipedia, the free encyclopedia. First go to the Protein results to check if the query returned the ncbi proteins. You'll have to use a field for specifying the organism and for specifying that want to retrieve mRNA sequences. Look in the Search details box how this filter is translated in the actual query that is used to search the database:. By using this site, you agree to the Terms of Use and Privacy Policy. On the GQuery page you see a list of all the databases that are searched by GQuery, grouped according to topic. Online databases National Institutes of Health Biological databases Government-owned websites Scholarly search services. We will only search in the Organism field of the Genbank records for the search term hiv. Gquery screenshots may not be up-to-date. Ina client-server version of the software provided connectivity with the internet. The Entrez front page provides, by default, access to the global query. Some textbooks are also available online through the Entrez system. When you go to gquery Search ncbi of the last query of the previous exercise, you see how this filter is translated: GQuery is the name of the search portal that searches gquery all NCBI databases non-sequence databases will be covered later into more detail. The filters will retain records that contain mRNA sequences and that were submitted in That's because the mRNA filter is a field that is specific for this database. Look in the Search details box how this filter is translated in the actual query that is used to search the database: But more importantly, it allows very finetuned searching on the annotations of sequences. The search did indeed return proteins with a length between and amino acids. The major advantage of GQuery is the common interface to the different databases:

The filters will retain records that contain mRNA sequences and that were submitted in The GQuery results page returns the same list of NCBI databases, together with the ggquery of records found in each database containing the word hiv. You see that the search on the Nucleotide database returned sequences with a length between and base pairs. It is widely used in the field of biotechnology as a reference tool for students and professionals alike. InEntrez bookshelf was released and inthe Entrez Gene database was developed.

All databases indexed by Entrez can be searched via a single query string, supporting boolean operators and search term tags to limit parts of the search statement to particular fields. First go to the Protein results to check if the query returned the correct proteins. When you want to use the accession numbers of the results to search in ENA, you cannot include RefSeq accession numbers since they are not used nor recognized by ENA. You only see results for the Nucleotide database. That's because the mRNA filter is a field that is specific for this database. To download the Accession list: When you go to the Search gqueryy of the last query of the previous exercise, you see how this filter is translated: To find all proteases you need to search for protease To exclude mcbi from hiv viruses you need the NOT operator To specify that you want to exclude proteases originating from hiv viruses you need to use the Nncbi field So you search for protease NOT hiv [Organism]. Activate the Sequence length filter and set the range to to

We will only search in the Organism field of the Genbank records for the search term gquery. You can use the same syntax in the GQuery search if you want to search all databases gqueru sequences in this length range. Now check the results for the Nucleotide database.

Remove all filters set in the previous exercise Do an advanced search: When you go to the Search details of the last query of the previous exercise, you see how this filter is translated: It is widely used in the field of biotechnology as a reference tool for students and professionals alike. You'll have ncbi use fields to gsuery this one. Type the search term hiv in the box and click Search. Entrez also provides a similar interface for searching each particular database and for refining search results. Not only searches are similar but also the result pages of all NCBI databases look the same in Entrez.
