[BioC] blast probe clusters when using Affymetrix Gene Array Strips

[Joao Sollari Lopes]

Hi,

I am using Zebrafish Gene 1.1 ST Array Strip, I have found some 
transcript clusters that are differentially expressed but are not 
annotated (although they belong to the "main" design of the array). I 
would like to blast them, but I am not sure what to blast as each 
transcript cluster has various probes associated. Should I blast them 
all individually? I have read about "probe set target sequence" 
(https://stat.ethz.ch/pipermail/bioconductor/2004-March/004250.html), 
but I am not sure if it applies to the Gene Array Strip. If it does, how 
can I obtain these sequences?

Thanks,
Joao
