[Bioperl-l] Fwd: Changes to NCBI BLAST and E-utilities.

Fri Feb 5 16:16:29 UTC 2010

Thanks Mauricio.  I think the only thing of impact will be the BLAST+ stuff (and Mark has developed a wrapper for it).  We'll need to update the SearchIO parser, so any BLAST+ output examples would be tremendously helpful.

We are not sure how many of your users use BioPerl with the BLAST binaries, my understanding is that many use BioPerl to to remote BLAST. However, there isa change to the BLAST results in Text and presumably HTML. This could have an effect on any parsers which scrape these formats and do not use XML. For obvious reason, we want to support only the XML format for parsing, but we thought we should give you heads up on this.

Effective on June 1, 2010, all E-utility requests, either using standard URLs or SOAP, must contain non-null values for both the &tool and &email parameters. Any E-utility request made after June 1, 2010 that does not contain values for both parameters will return an error explaining that these parameters must be included in E-utility requests.

These usage policies are designed to prevent excessive requests from a small group of users from reducing or eliminating the wider community's access to the E-utilities. NCBI will attempt to contact a user at the e-mail address provided in the &email parameter prior to blocking access to the E-utilities.

Based on past experience, we anticipate that most of our users should be able to make the necessary changes before the June 1, 2010 deadline. If you have any concerns about making these changes by that date, or if you have any questions about these policies, please contact eutilities at ncbi.nlm.nih.gov.
