   E-Mail Searching of Sequence Databases at NCBI         8/12/92


   The National Center for Biotechnology Information (NCBI), National
   Library of Medicine, is now providing e-mail server access for
   sequence similarity searching (BLAST) and for record retrieval
   from sequence databases.

   The BLAST e-mail server accepts either a DNA or amino acid query
   sequence in FASTA format, runs the search against a combined
   (non-redundant) or a single database, and returns the results in
   a mail message.

   The RETRIEVE e-mail server accepts single or multiple text strings
   (locus names, accession numbers, keywords, author names, etc.) as
   queries, runs an IRX search against a specified database, and
   returns the matching full record(s) as a mail message.


   To receive documentation on how to use the servers, send a mail
   message with the word 'help' in the body of the message to:

       BLAST server:          blast at        

       RETRIEVE server:       retrieve at
