class Bio::NCBI

Gets default email address for Entrez (eUtils).

Returns

String or nil

   # File lib/bio/io/ncbirest.rb
50 def self.default_email
51   ENTREZ_DEFAULT_PARAMETERS['email']
52 end

Sets default email address used for Entrez (eUtils). It may also be used for other NCBI services.

In www.ncbi.nlm.nih.gov/books/NBK25497/ NCBI says: “The value of email should be a complete and valid e-mail address of the software developer and not that of a third-party end user.”

By default, email address of BioRuby staffs is set.

From the above NCBI documentation, the tool and email value is used only for unblocking IP addresses blocked by NCBI due to excess requests. For the purpose, NCBI says: “Please be aware that merely providing values for tool and email in requests is not sufficient to comply with this policy; these values must be registered with NCBI.”

Please use your own email address and tool name when registering tool and email values to NCBI.

Arguments:

In www.ncbi.nlm.nih.gov/books/NBK25497/ NCBI says: “The value of tool should be a string with no internal spaces that uniquely identifies the software producing the request.”
