Reload of IFIPAT, IFICDB, and IFIUDB
IFI Patent Database (IFIPAT), IFI Comprehensive Database (IFICDB), and IFI Uniterm Database (IFIUDB) have been reloaded on STN. These databases cover abstracts and claims of U.S. patents from 1950 to the present and are produced by IFI Patent Intelligence.
Search and display enhancements in this reload include:
- Addition of the DISPLAY SCAN format to help evaluate usefulness of answer sets
- Removal of GI (Graphics Information) from previously available display formats except ALL, ALLTX, and IALL
- Searchable series code information in the Application Number (AP.SC) field and displayable in the Application Information (AI) field.
Data enhancements in the reload include:
- Indexing for more than 70,000 additional published applications
- Enhanced indexing with new terms for various green technology areas such as biofuels and biodegradable polymers
- Back file posting for new indexing terms
- Back file postings for many FDA Orange Book listed patents
Display SCAN toegevoegd aan databases
To facilitate easier review of search results in a multifile search environment, the DISPLAY SCAN format has been added to the following databases:
EMBAL, EMBASE, LEMBASE, ENCOMPLIT, ENCOMPLIT2, ENCOMPPAT, ENCOMPPAT2, IFICDB, IFIPAT, IFIUDB, MEDLINE®, LMEDLINE
The DISPLAY SCAN format can be used to view answers from an L-number answer set at no charge. Answers are displayed in a predefined format, in random order, and without answer numbers. The predefined formats vary according to the database.
Databases verwijderd van STN
De volgende databases zullen van STN worden verwijderd:
REGISTRY spectra niet meer automatisch toegevoegd aan verschillende formaten
In response to customer and training staff requests, spectra will no longer be automatically included in the following CAS REGISTRY display formats: PROP, FIDE, ALL, IALL. Automatic spectral display will continue to be offered in the MAX format. In addition, individual spectra may continue to be displayed by clicking links in the Experimental Properties (EPROP) table (at no additional cost), or by using one of the SPEC formats (SPEC, SPEC.IR, SPEC.H1NMR, etc.). See HELP COST in REGISTRY for cost information.
CHEMCATS® Accession Number Assignment Change
The CAS-assigned CHEMCATS Accession Number (AN) processing will change to increase the AN limit to allow continued updating of the CHEMCATS file.
This change will affect the order in which CHEMCATS records display on STN® and in SciFinder® (client version), but will not affect the record order in the web version of SciFinder. The content of the CHEMCATS records will not be affected.
DGENE, USGENE and PCTGEN
A new sequence sorting feature for BLAST answer sets from DGENE, USGENE and PCTGEN is available since November 30, 2009. This new sorting option is a great support for reviewing large sequence answer sets and makes the identification of relevant sequences much more efficient and reliable. The enhanced sorting functionality allows you to sort a BLAST answer set according to local percent identity (IDENT). Additional sorting with this BLAST parameter is especially useful to identify short, highly similar sequences with a low overall homology score.
The new percent identity field IDENT is available for sorting and display purposes. Ideally it can be used in combination with the conventional homology sorting parameter SCORE. Using both parameters simultaneously for sorting generates answer sets which are more easy to review. For this kind of dual sorting either of the two BLAST parameters can be specified to be the premier sort parameter. On top of this, customers have the choice to group sequence records into invention families using the FSORT command. When FSORT is applied to an answer set previously sorted by IDENT and SCORE, the sort order is retained for each family. Thus the new sorting option adds additional flexibility to the display of BLAST answer sets.
The new sorting feature is available for all online and batch BLAST search results, and also for BLAST alert results in all three databases.
