The EMBL Nucleotide Sequence Database was frozen to make Release 60
on 03-SEP-1999. The release contains 4,719,266 sequence entries comprising
3,543,553,093 nucleotides. This represents an increase of about 21% over
Release 59. A breakdown of Release 60 by division is shown below:

In *addition* to the cumulative.dat.gz files we make available on our FTP server, we now also split that dataset into smaller parts, namely:
cum_1.dat.gz all the cumulative file except the data in files below cum_est1.dat.gz ESTs cum_htg1.dat.gz HTG cum_hum1.dat.gz human (non-gss,non-HTG, non-EST) cum_gss1.dat.gz GSSWe chose this data division: - because it represents the current major division of data in the updates, or our best guess about what will happen in the coming months. - to try to keep the files below 2GB for as long as possible, eg before needing cum_hum2 etc - to avoid frequent changes. These filenames should last a while and contain some data even soon after a new full release. SRS icarus files (for example) should not need constant changing, and when they do we should be able to see it coming well beforehand.
Those who 'mirror' our ftp.ebi.ac.uk/pub/databases/embl/new directory may wishto have either the full cumulative.dat.gz or the cum_* set ignored, in order to save some netwidth. The data contained is the same - we build the cum_* files from the cumulative.dat.gz file afresh each day. There is no correspondence between, say, cum_est1.dat and the est1.dat file of the full release.
The EBI SRS server now has the EMBLNEW dataset using these cum_* files.
1.2 Old sequence identifiers (NID, PID) phased out
Nucleotide Sequence Identifiers (NID) and Protein Sequence Identifiers (PID) until now have been represented in the NI linetype of the EMBL flat-file and the /db_xref qualifier, respectively.
NID Example:
ID MTRECACAN; standard; DNA; PRO; 2737 BP. XX AC AJ000012; XX NI e1169844 XX PID Example: FT CDS 302..2674 FT /db_xref= "PID:e191449"These identifiers are integer values assigned randomly everytime the underlying nucleotide or protein sequence changes. To adopt a comparable scheme of sequence identifiers for both nucleotide and protein sequences, the DDBJ/EMBL/GenBank Database Collaboration has earlier this year introduced a new form of nucleotide and protein sequence identifiers. The new format for nucleotide and protein sequence identifiers consists of a stable part which will not change, and a version part which will be incremented whenever the underlying nucleotide sequence or protein translation changes. The new form of identifiers allows external databases easier tracking of changes to nucleotide and protein sequence identifiers. The new sequence identifiers are maintained collaboratively (DDBJ/EMBL/GenBank) and are portable amongst databases, thus allowing users to access an exact version without being tied to only one of the collaborative databases. During a transition phase (6 months) both the old (NI/PID) and new forms (SV/protein_id) of identifiers have been provided.
Starting from this release (Sep 1999) only the new form of sequence identifiers will be included.
Example: Nucleotide Sequence Identifier ID BSELBGEN; standard; DNA; PRO; 2196 BP. XX AC X99911; XX SV X99911.3 XXProtein Sequence Identifier
FT CDS 205..2109 FT /protein_id="CAA68184.1" FT /db_xref="Swiss-Prot:Q46497" FT /transl_table=11 FT /gene="selB" FT /product="selenocysteine-specific elongation factor" FT /function="replaces EF-Tu during translation"For further details on nucleotide and protein sequence identifiers please see previous release notes.

DR RZPD; IMAGp998G19998; 16-Jul-1999.1.5 Database Files
In order to keep the size of the data files within reasonable limits for handling purposes, additional division files will be added in subsequent releases as appropriate.
In order to keep the size of the data files within reasonable limits for handling purposes, we have split the EST division into 30 files. (EST1.DAT - EST30.DAT).
In order to keep the size of the data files within reasonable limits for handling purposes, the GSS division has been split into 11 files (GSS1.dat - GSS11.dat).
A consortium of 5 major sequencing centres (Sanger, Baylor,WashU, Whitehead, DOE) are involved in establishing the draft human genome. The Sanger Centre (UK) is the European participant producing about 33% (~1 Gb) of the high-through-put draft genome sequence data (HTG phase 1) including high-throughput automatic annotation. The project is expected to be completed by February .
An experimental directory representing genome data has been available from the EBI anonymous FTP server in directory
including a number of files for each genome: a file listing construct information and all accession numbers relevant to the project, the complete single entry in EMBL format (DNA and features), the complete DNA sequence in FASTA format, e.g.
in ftp://ftp.ebi.ac.uk/pub/databases/embl/genomes/Eubacteria/bsubtilis/
README
bsubt.con
bsubt.embl
bsubt.embl.Z
bsubt.fasta
bsubt.fasta.Z
Efforts are now undertaken to develop a new database division (CON) to represent these complete genomes, or other long sequences constructed from segment entries. The CON division will contain construct information, accession numbers and sequence locations involved in building the constructs.
Additionally, the according complete entries including descriptive information
, references, features, DNA sequence will be linked, searchable and retrievable
through SRS and available for BLAST and FASTA homology searching.
2.2 Replacement of organelle-related qualifiers with new qualifier
/organelle
A large variety of organelle qualifiers currently exist: /mitochondrion, /chromoplast, /chloroplast, etc. Starting with EMBL Release 62 (March 2000), these qualifiers will all be incorporated into a single new qualifier, with a controlled value format. The preliminary description of this qualifier is as follows:
Qualifier /organelle="" Definition type of membrane-bound intracellular structure from which the sequence was obtained Value format mitochondrion, nucleomorph, plastid, mitochondrion:kinetoplast, plastid:chloroplast, plastid:apicoplast, plastid:chromoplast, plastid:cyanelle, plastid:leucoplast, plastid:protoplast, Examples /organelle="mitochondrion" /organelle="nucleomorph" /organelle="plastid" /organelle="mitochondrion: kinetoplast" /organelle="plastid: chloroplast" /organelle="plastid: apicoplast" /organelle="plastid: chromoplast" /organelle="plastid: cyanelle" /organelle="plastid: leucoplast" /organelle="plastid: protoplast" Comments modifier text limited to values from controlled list3 SEQUENCE SUBMISSION SYSTEMS
3.1 Checking Sequence Data For Vector Contamination
We urge submitters to remove vector contamination from sequence data before submitting to the database. To assist submitters the EBI is providing a Vector Screening Service using the latest implementation of the BLAST algorithm and a special sequence databank known as EMVEC. EMVEC is an extraction of sequences from the SYNthetic division of EMBL containing more than 2000 sequences commonly used in cloning and sequencing experiments. EMVEC is by no means a complete vector databank but EBI believes it is representative of the kind of material used in modern sequencing and should be useful to submitters. The databank will be updated with each release of EMBL and made publicly available on the EBI's ftp (ftp.ebi.ac.uk) server for those who wish to have it.
The interactive WWW service can be found at:
http://www.ebi.ac.uk/submission/webin.html
http://www.ebi.ac.uk/blastall/vectors.html
The results will list sequences producing significant alignments and associated information like vector name, score, alignment etc
3.2 WebIn - WWW Sequence Submission System
WebIn is the preferred WWW Sequence Submission System for submitting nucleotide sequence data and associated biological information to the EMBL Nucleotide Sequence Database at the European Bioinformatics Institute (EBI). To access WebIn at the EBI please use the following URL:
http://www.ebi.ac.uk/submission/webin.html
Database entries created by the new WWW submission tool and submitted to the EMBL Nucleotide Sequence Database at the EBI will be exchanged and shared among the International Collaboration of Nucleotide Sequence Databases (DDBJ/EMBL/GenBank).
WebIn guides the user through a sequence of WWW forms allowing the submission of sequence data and descriptive information in an interactive and easy way. All the information required to create a database entry will be collected during this process:
1 Submitter Information
2 Release Date Information
3 Sequence Data, Description and Source Information
4 Reference Citation Information
5 Feature Information (e.g. coding regions, regulatory signals etc.)
EBI staff will process data submissions within 2 working days and send the database accession number(s) assigned to your data to your e-mail address.
With the aim to make bulk sequence submission highly efficient and less time consuming for the submitters, a prototype of a new web-based bulk sequence submission system can now be accessed from WEBIN. Authors planning to submit a large number of similar sequences (i.e.,>25) are presented with an option for "Bulk WebiN Submission". When choosing the bulk path, submitters carry on the usual WEBIN submission procedure until having finished a first and single representative sequence. During the submission process database staff will interactively assist in making the submission of this specific data as convenient as possible, thus saving the author the time and effort required to complete numerous submission events individually.
Alternatively, authors planning to submit very large numbers
of similar sequences should contact the database before submitting the
data. Database staff will then assist in making the submission of this
data as convenient as possible, thus saving the author the time and effort
required to complete numerous submission events individually. When contacting
database staff, authors should indicate the number of sequences they plan
to submit. Database staff will create series of templates and communicate
these to the author for completion with just the information unique to
each sequence required. These templates, once resubmitted, will then be
processed en masse by
database curators.
Please contact database staff if you require further information.

3.5 Sequence Alignment Submissions
The EBI accepts submissions of alignment data (e.g. from phylogenetic and population analysis etc..) of both nucleotide or amino-acid sequences. This data is assigned an alignment number (e.g. ds38200) by database staff which is then communicated to the submitter. We suggest that this number is quoted in the resulting publication.
Alignment data and associated information are made available via EBI's network servers (see below).
ALIGNMENT FORMATS:
As well as your alignment data we require information describing your alignment (see table below) Please provide information for all fields.
| Description Field | Information required |
| TITLE: | Title of alignment |
| SUBMITTER: | Name, Affiliation, Phone, Fax, Email |
| RELEASE DATE: | Public Immediately / if Confidential please provide hold date |
| CITATION: | If known please provide complete Author list, Title, Journal, Year of publication, Page numbers |
| ALIGNMENT METHOD: | Method of alignment and format submitted, parameters of alignment sequences used (if appropriate) |
| DESCRIPTION OF SYMBOLS: | e.g. Gaps indicated by a dash '-' |
| DESCRIPTION OF ALIGNMENT: | Describe sequences aligned, including accession numbers (if known) and abbreviation of clones or taxon used in alignment file. If your alignment contains sequences derived from multiple taxoonomic sources, please provide the full name of each organism |
| FILE FORMAT: | We are currently updating and improving both the access to and alignment
output of this archive due to an increase in the submission of alignment
data. The compilation of text files and the issue of format standardisation
are undergoing review and are being discussed by the database staff, external
users and experts in the field.
We suggest submission in STANDARD ALIGNMENT FORMATS eg. (NEXUS, PHYLIP, ClustalW etc) or Sequin output. |
A sample alignment in NEXUS format can be viewed at ftp://ftp.ebi.ac.uk/pub/databases/embl/align/ds32096.dat
NOTE 1: Alignments can be created within Sequin or imported into Sequin from files in a standard alignment format like NEXUS or PHYLIP.
NOTE 2: If reporting new primary sequence data, we suggest that you submit the complete individual sequence files (e.g. via Sequin or Webin), in order to include the sequence data as individual entries in the database. If gaps have been introduced for the alignment, please leave them out when sending the individual sequence files.
SENDING ALIGNMENT DATA to the EMBL Nucleotide Sequence Database
Sequence Alignment Data can be sent to the Nucleotide Sequence Database
by Electronic mail to DATASUBS@EBI.AC.UK
ACCESSING ALIGNMENT DATA
Alignment data and additional information are available via the EBI
servers:
EBI WWW server: ftp://ftp.ebi.ac.uk/pub/databases/embl/align/
EBI FTP server: by anonymous FTP from FTP.EBI.AC.UK in directory /pub/databases/embl/align

4 CITING THE EMBL NUCLEOTIDE SEQUENCE DATABASE
We encourage authors to include a reference to the EMBL Database in publications related to their research.
When citing data in the EMBL Database, we suggest to give the according primary accession number(s) and the publication in which the sequence first appeared. For unpublished data, we suggest to contact the original submitters for recent publication information or revisions of the data.
We suggest to also provide a reference for the EMBL Database itself. Our recent publication in Nucl. Acids Res., 1999, Vol. 27 (1), 18-24., which describes the EMBL database, should be cited:
Stoesser, G., Tuli, M.A., Lopez, R., and Sterk, P.. The EMBL Nucleotide Sequence Database Nucl. Acids Res., 27:18-24(1999)
Example: The numbers in parentheses refer to the REFERENCE in the EMBL database entry, and to the EMBL citation above.
"Sequence entry X56734 (1) has been retrieved from the EMBL Database (2) and showed significant sequence similarity to ..."
(1) Oxtoby E., et al., Plant Mol. Biol. 17:209-219(1991).
(2) Stoesser, G., et al., Nucl. Acids Res. 27:18-24(1999)
Computer users with access to Internet (directly or via a gateway) can obtain copies of database entries, documentation or the data submission form, by sending commands to a file server running on the computer systems at EBI. New and updated EMBL nucleotide sequence entries are made available on the server on a daily basis.
To use this facility, send file server commands (as electronic mail) to the address Netserv@EBI.AC.UK. Each line of the mail message should consist of a single file server request.
The most important file server request, to get started, is:
HELP
If the file server receives this command, it will return a help file to the sender, explaining in some detail how to use the facility. For example, to request a copy of the data submission form and the nucleotide sequence with accession number X12399, use the commands:
GET DOC:DATASUB.TXT
GET NUC:X12399
The file server offers various other services, (eg., access to nucleotide and protein sequence data, protein structure data, software), details of which are provided in the HELP file.
An alternative method of accessing the EBI archives is to use the Internet file transfer protocol (ftp). Researchers with direct access to the Internet can use the FTP program on their local machine to connect to the host FTP.EBI.AC.UK and enter the user name "anonymous" and their email address as password. The directory pub/help contains detailed information about the data available from the EBI anonymous FTP server which includes the complete EMBL Nucleotide Sequence Database releases as well as daily and weekly updates and a cumulative update file (in UNIX-compressed format) in the following directories:
EMBL quarterly release: pub/databases/embl/release
EMBL updates: pub/databases/embl/new
5.3 World Wide Web (WWW) Server
The EBI operates a WWW server with URL http://www.ebi.ac.uk/ which gives access to information about the EBI and it's products and services. Nucleotide sequences can be retrieved by a simple query by accession number, or more complex queries can be contructed using an SRS WWW databank browser. Nucleotide sequences can also be submitted to the database using the interactive submission system WebIn at URL:
http://www.ebi.ac.uk/submission/webin.html
The EBI offers two network servers for sequence similarity searches via electronic mail or interactive WWW forms:
| FASTA | based on W. Pearson's FASTA algorithm. Allows local similarity searches of protein and nucleotide sequence databases. Send "help" to fasta@ebi.ac.uk or use URL http://www.ebi.ac.uk/fasta33/ |
| BLAST | based on the NCBI and WU-BLAST software Send "help" to blast@ebi.ac.uk or use URL http://www.ebi.ac.uk/blast2/ |
| BLITZ | BLITZ allows very fast searches of protein sequence databases for local similarities using an exhaustive Smith-Waterman matching algorithm. Compugen's BIC_SW software is running on a Biocellerator (BIC-2) Send "help" to Blitz@EBI.AC.UK or use URL http://www.ebi.ac.uk/bic_sw/ |
