Subject:      Genbank weekly updates

Dear GCGers:

     I don't recall having seen anything on INFO-GCG concerning the transfer
of Genbank weekly updates from Intelligenetics to NCBI.  The following is my
question to NCBI and their answer.  This means modifications to the GCG
FTP Utilities programs. Perhaps GCG (are you listening?) can suggest the
proper modifications.

  Paul,

     We are posting two kinds of GenBank flat file updates on anonymous FTP
  on the host:  ncbi.nlm.nih.gov:  the first is a cumulative file that
  represents all new or changed entries since the last public release.
  That is in:  ./ncbi-genbank/daily and is the file 'gbcu.flat.Z'.

     The other update is a non-cumulative update consisting of new or
  changed entries for a particular day.  These files are date-stamped and
  are in the directory:  ./ncbi-genbank/daily-nc.  Here's what the directory
  looks like:

  ncbi: /ncbi-data/ftp/ncbi-genbank/daily-nc> ls -lt
  total 626
  -rw-rw-r--  1 cavanaug    23376 Sep 11 04:54 bbnc0911.flat.Z
  -rw-rw-r--  1 cavanaug    50126 Sep 10 05:45 bbnc0910.flat.Z
  -rw-rw-r--  1 cavanaug   486867 Sep  7 04:48 bbnc0907.flat.Z
  -rw-rw-r--  1 cavanaug     6666 Sep  3 03:52 bbnc0903.flat.Z
  -rw-rw-r--  1 cavanaug    10152 Sep  2 04:04 bbnc0902.flat.Z
  -rw-rw-r--  1 cavanaug     6843 Aug 27 03:56 bbnc0827.flat.Z
  -rw-rw-r--  1 cavanaug    11877 Aug 25 01:16 bbnc0825.flat.Z
  -rw-rw-r--  1 cavanaug     3182 Aug 20 05:30 bbnc0820.flat.Z
  -rw-rw-r--  1 cavanaug    14094 Aug 18 06:03 bbnc0818.flat.Z
  -rw-rw-r--  1 cavanaug    11877 Aug 13 05:35 bbnc0813.flat.Z


     Note there are gaps in the days on which files are released.  This
  results from days on which we do not release records from the internal
  to the public database.  Generally, you'll find that in a given week
  there will be two or three update files.  At the moment the
  updates reflect only entries from the NCBI backbone; after September
  30, data from LANL will be folded in so these files will represent
  true updates to NCBI-GenBank.


     Hope this helps, let me know if you have any further questions.


     Regards,

     Dennis Benson
