Hello Andigoni,
To confirm, the data is being extracted using "Get Data -> UCSC Main"
using the Table browser for the hg16 reference genome?
If so, I can let you know that the reference genome itself remains the
same through time. However, annotation tracks may or may not be
updated.
Genbank track update frequencies are incremental daily additions and
add/remove/change at full releases.
From your numbers, it seem like the data is coming from RefSeq Genes.
This track was last updated on "2012-04-07". This can be seem at UCSC
when browsing the track's description page, the last line of the top
section: "Data last updated:". The dates for the corresponding files
on
their downloads server will also reflect updates (server updated
weekly).
Unfortunately, there isn't a straightforward way to get back to your
prior data unless you have it saved. If you have the exact date of
your
original data pull, you may be able to reconstruct part of it by
mining
GenBank directly, but this would be non-trivial and involve your own
methods/tools outside of Galaxy.
Hopefully this helps to explain the data content. If you have comments
or questions about how tracks are processed at UCSC (including this
question, they may have a creative solution), their team can be
reached
at: http://genome.ucsc.edu/contacts.html
Going forward, please use our mailing list for questions.
Thank you!
