DGENE, USGENE, and PCTGEN: STN biosequence searches with enhanced performance

23. May 2011

FIZ Karlsruhe has enhanced the performance for biosequence searches in the databases DGENE, USGENE and PCTGEN. Searches (RUN GETSEQ, RUN GETSIM, RUN BLAST, BATCH search) now run to completion in a fraction of the time you have been used to.

The BLAST suite of programs has been upgraded to a newer version. mpiBLAST 1.5.0. is being employed to achieve the considerable performance gains. For more information about the program, please visit: http://www.mpiblast.org/.
Since mpiBLAST 1.5.0. uses the more recent BLAST version 2.2.15 new parameter options become available.

For more detailed information on the BLAST algorithm consult the NCBI documentation at:
http://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Web&PAGE_TYPE=BlastDocs

The online helps containing information on the BLAST parameter settings, default and valid values etc. have been updated. Please see HELP OPTIONS and HELP NCBI.

The general default options as well as search behaviour have not changed. Thus, you should not see noticable changes to your search results when using default parameters. Yet, the range of accepted values may have changed.

Please note that although now running faster the underlying program versions for the GETSEQ and GETSIM searches have not changed.
