| 11/25 | Electronic PCR |
Electronic PCR is
now available. PCR-based sequence tagged sites (STSs) have been used as
landmarks for construction of various types of genomic maps. Using
"electronic PCR" (e-PCR), these sites can be detected in DNA sequences,
potentially allowing their map locations to be determined. |
| 11/14 | Sequin, Release 1.71 |
A new release of
Sequin, a sequence
submission tool, is now available. Version 1.71 features improved handling of
phylogenetic sets of sequences and also allows users to update their own
pre-existing database records. |
| 11/04 | dbGSS Announced |
The Database of
Genome Survey Sequences (dbGSS) is now available. This database contains
more detailed information than the corresponding records in the GSS Division
of GenBank. |
| 10/24 | Human Gene Map |
The Gene Map of the
Human Genome published in the October 25 issue of Science is
available. This map shows the chromosome location of over 16,000 human
genes with links to the underlying sequence and map data. |
| 10/04 | Sequin |
Sequin, a
stand-alone sequence submission tool, has a new release with
several enhancements, including a repeat finder and ORF finder. New
documentation and a tutorial are available, both on the Web and in NCBI's
newsletter. |
| 09/27 | ORF Finder |
The Open Reading
Frame (ORF) Finder is a graphical analysis tool that finds
all open reading frames in a user's sequence or one already in the database
of a selectable minimum size. |
| 09/06 | Virological Software |
Software for analyzing animal trials and calculating infectious and
50% inhibitory doses is now available. The
programs VacMan and
ID-50 can now be downloaded as self-extracting archives for either IBM
or Macintosh computers. |
| 08/23 | Complete Genome, Methanococcus jannaschii |
The complete genome sequence and annotation of Methanococcus
jannaschii, prepared by The Institute for Genomic Research
(TIGR) is now available in
Entrez Genome,
as well as in GenBank, where the 1.7-megabase sequence
has been separated into 150 records of approximately 11,000 bp each.
The graphical view (as well as a link to underlying data)
of the complete genome is present in Entrez Genome,
along with the extrachromosomal elements 1 and 2. The complete sequence
is also available by anonymous
FTP;
see the README
file for a description of the various files in the genomes division directory. |
| 08/20 | Batch Entrez |
Downloading large numbers of sequence records from Entrez is
now possible through 'Batch Entrez'.
User can specify a download for an entire set of records for a given organism or for a set of
accession numbers. The data are saved to a file on the user's computer. |
| 08/05 | Saccharomyces cerevisiae Database |
A new database has been added to the
BLAST databases: all the
nucleotide sequences from the yeast
(Saccharomyces cerevisiae) genome sequencing project and their encoding
amino acid sequences can now be searched with the BLAST suite of programs. |
| 07/26 | Cn3D in Entrez |
A major new release of Network Entrez is now available. Release 5.0
contains Cn3D, a new
3D structure viewer integrated into Network Entrez. |
| 07/15 | BLAST2 |
The BLAST2 network service is now available on the FTP site
without registration. Three clients for multiple platforms
are available: blastcli has a convenient graphical interface and
produces the "traditional" BLAST output; blastcl2 is a command-line
client (meant mostly for UNIX) that also produces the traditional
BLAST output; and PowerBlast produces a one-to-many alignment, allows
filtering by organism, and allows a gapped alignment as a
post-processing of the BLAST results. Users of the older
Experimental BLAST Network Service (with the exception of GCG users,
who are still required to register and use the older program) are
encouraged to switch to this newest version. |
| 05/21; see also 11/14 | Sequin |
Sequin is
a program for submitting and updating GenBank entries.
It is designed to simplify the sequence submission process, provide
graphical viewing and editing options, and allow submission of segmented
entries. Sequin automatically adjusts feature table positions as the
sequence is edited. Versions of Sequin
are available through FTP
for the Macintosh, PC/Windows, UNIX, and VMS. |
| 05/21 | PowerBlast |
PowerBlast is a new network BLAST application for automated
analysis of genomic sequences. It combines BLAST searching with
filtering for low complexity regions and repeats. It can generate
organism-specific output and compute optimal, gapped alignments. The
results are displayed graphically and textually as multiple alignments,
with annotated features superimposed on the aligned sequences.
Versions of PowerBlast are available through FTP for the
Macintosh, PC, SunOS, and Solaris. |
| 05/06 | WWW BLAST |
The WWW BLAST page has been
extensively revised. It now has both a
simplified "Basic" Blast Search, allowing a user to search with the
default parameters, as well as an "Advanced" page, where users may set
BLAST parameters. An email option allows a user to receive results in
a convenient form. |
| 04/10 |
WWW Entrez |
WWW Entrez now provides graphical
views of nucleotide and protein sequences and access to the NCBI Genomes database, which
contains graphical views of sequences and chromosome maps. Click on
"Graphical view" from an Entrez document summary or click on the
"Graphic" button from a sequence report. |
| 03/12 | Mouse/Human Homology |
The Seldin/Debry
Mouse/Human Homology
Relationships page presents a table comparing genes in
homologous segments of DNA from human and mouse sources, sorted by
position in each genome. |
| 03/07 | Complete Genomes |
An NCBI research project,
Complete Genomes, presents the results of
analyses of complete genome sequences. The analyses for the genomes of
Haemophilus influenzae, E. coli (75%), and Mycoplasma
genitalium are now available. |
| 03/08 | BLAST Databases |
Changes to the BLAST Databases (February 20
announcement superseded by that of March 8.) |
| 02/15 | Homepage Reorganization |
Major reorganization of
the NCBI homepage
with new top-level links to additional databases and services. |
| 02/07 | International Database Collaboration |
The International Nucleotide
Sequence Database Collaboration page describes current projects and
provides links to the sites. |
| 01/30 | NCBI Structure Group |
The NCBI Structure Group
(Steve Bryant) has a new page providing
access to their structure research, the PKB and MMDB databases, and
threading software. |
