Why can't I find a published sequence?
We maintain Genbank on helix, and only those parts of EMBL that
are not present in Genbank. There are several possible reasons
why you might not find a published sequence:
- Are you searching in the right database? If you are using
GCG's Lookup program, you can search 'Genbank' &/or 'GB_New'.
The 'Genbank' database contains the last release of Genbank.
The 'GB_New' database contains all updates since that release,
upto the previous night. If the data were published recently,
the sequence might be in GB_New rather than Genbank.
- Are you searching by accession number? If so, make sure
you are using the Genbank accession number rather than EMBL...
- In the Lookup program, try searching 'All text' for
words relevant to your sequence, in case the published
accession number has a typo.
- Authors sometimes request that their data be held in confidence
until after publication, even though they have already been
assigned an accession number. This may create a delay in the
release of the data.
