hi all,

i'm debating on whether to download GO annotations through biomart or just
get them from GO directly.  The advantage to me of getting it through
biomart is that i can get the ID format i need right away.  However, when i
compare the annotations from Biomart, versus GO directly, there seems to be
a huge discrepancy, mainly in two areas:

1) # of annotations - direct download from GO seems to obtain hundreds of
thousands more annotations.
2) evidence types - biomart seems to not use a lot of the evidence codes
that i find from the direct-GO approach, mostly from the 'computational
analysis' evidence codes.


both #1 and #2 leads me to think Biomart doesn't update its annotations
often, but i'm not sure if i'm just not grabbing it correctly -- does
anyone know how often they update?
