NOTIFICATION OF CHANGE 2/9/2007:

A new FTP directory, ftp://ftp.ncbi.nlm.nih.gov/genomes/MapView,
has been created to distribute data displayed in the MapViewer.
The directory includes all current and archived builds of organisms
that currently have mapview data in ftp://ftp.ncbi.nlm.nih.gov/genomes/  
as well as organisms displayed in MapViewer that did not previously
have directories in ftp://ftp.ncbi.nlm.nih.gov/genomes/.

Existing mapviewer files under ftp://ftp.ncbi.nlm.nih.gov/genomes/ have 
been replaced with links to the new locations.

For more information, please refer to ftp://ftp.ncbi.nlm.nih.gov/genomes/MapView/README

NOTIFICATION OF CHANGE:

This new FTP directory has been created to distribute data generated 
by analysis and/or additional processing at NCBI.  The new directory 
contains sequence records that are generated and maintained by NCBI.
This includes records generated by the NCBI Reference Sequence (RefSeq) 
project, including complete genomes/chromosomes, contigs, and 
reference sequence mRNAs and proteins.  

In addition, other data sets that are provided in NCBI resources 
will also be redistributed in this area.  These include data 
presented in the Map Viewer as well as LocusLink data. 

Some data that was originally provided in the
ftp://ftp.ncbi.nlm.nih.gov/genbank/genomes/  FTP directory 
will now be provided in this new location.  This transition 
will occur gradually. The first type of data to move are the 
NCBI generated Contig sequences.   Contig updates are no longer 
provided in the /genbank/genomes/ area.  The files in the 
original /genbank/genomes/ location will be retained temporarily 
as we transition to the new FTP area.

In the future, the ftp://ftp.ncbi.nlm.nih.gov/genbank/genomes/ area 
will be restricted to complete genome sequences that are submitted
to GenBank, such as bacterial or viral genomes, and that have not 
undergone additional analysis or processing at NCBI.
