Greetings GenBank Users,
Several of you reported that some records in October's Release 132.0 had
COMMENTs or /notes with line lengths that exceeded the 79-character maximum
for the GenBank flatfile format. A total of thirteen records were affected,
in seven release files:
Appended below are per-file lists of the accessions involved.
Our flatfile generator was recently enhanced to handle URLs embedded within
text strings in a smarter way. Unfortunately, the changes also introduced
a bug in line length calculation, when those text strings contain tokens of
For example :
"See <apehbb5ch>, <mnkhbb3rh>, <mnkhbb5rh>, <mnkhbb3ce>, <mnkhbb5ce>."
The bug was not detected by our usual QA procedures because there was an
extremely large number of COMMENT and /note diffs (100,000s), due to
unrelated code changes which removed extraneous whitespace characters.
We have added safeguards to our release-generation procedures which are
designed to prevent such problems from occurring in the future.
Our apologies for the inconvenience that this formatting error has caused
