[Gramene] Re: TAIR9 vs TAIR10 - mixup on naming, was: RE: Old versions?

[Ann Loraine]

Okay, it sounds like gramene needs to correct this.

Probably the person at gramene who downloaded the Arabidopsis data wasn¹t
aware that TAIR10 is really the same assembly as TAIR9. A lot of people get
confused about this. Or, they might have checked the actual data and
discovered a difference, despite what the documentation says.

Jonathan, since you are already providing validation services, could you
also provide some additional sanity checking of the data?

In this case, you could write something that determines whether two
reference assemblies with different names are in fact the same.

In addition, you could write something else that checks that two DAS sources
that serve the same genome sequence assemblies are indeed delivering the
same data. Confusion could easily arise if one source is delivering masked
sequence data but another one isn¹t.

Best,

Ann
