Greetings GenBank Users,
Twenty-nine records that should have been included in GenBank Release 120.0
are missing from the gb*.seq flatfiles due to a processing error in the
database that stores the flatfile versions of GenBank sequence records.
Rather than force these records to be redistributed via the GenBank Update,
we have decided to make them available via a supplemental file on the NCBI
ftp site:
ftp://ncbi.nlm.nih.gov/genbank/gbsup1.seq.gz
The creation dates of these records range from August 1997 through May 2000,
so all of them have been present in prior GenBank releases. Eighteen of the
records were (coincidentally) updated shortly after the 120.0 close-of-data,
so they are present in the nc1013 incremental GenBank Update, as well as
the GenBank Cumulative Update. Ten of the records (AF114856-AF114865) are
members of a segmented set whose first and last members are AF114855 and
AF114866. Since segmented sets are processed as a unit at NCBI, these two
are also in the supplemental file, bringing the total to 31 records. Complete
lists of the accessions involved are appended below.
The accession numbers of these records are *not* included in the list of
deleted accessions for 120.0 (gbdel.txt). So if you regularly process the
GenBank cumulative/non-cumulative updates to build a local database, and then
perform deletions based on the content of gbdel.txt, then you might not
need to process the supplemental file.
However, users who have completely rebuilt a local database based on the
GenBank 120.0 flatfiles *will* need to obtain the supplemental file, at
least for the 11 missing records that are not present in GenBank Updates
generated since the close.
The files that comprise the ASN.1 version of GenBank 120.0 are not affected
by this problem.
We apologize for any inconvenience that this dataflow problem might have
caused for our users.
