[BioC] AnnBuilder with custmerized GO annotation

[Xinxia Peng]

Hi All,

I am trying to reproduce the example given in 'Basic Functions of
AnnBuilder'. Here is what I got for the GO part of the annotation:

      GO                                          
 [1,] "GO:0004060 at E"                              
 [2,] "GO:0004060 at E"                             
 [3,] "NA"                                       
 [4,] "NA"                                        
 [5,] "GO:0008320 at NR;GO:0004866 at NR;GO:0006886 at NR" 
 [6,] "NA"                                        
 [7,] "NA"                                        
 [8,] "GO:0004060 at E"                              
 [9,] "NA"                                       

What do these after a GO term mean, '@E' or '@NR'?

What I am trying to do is to build an annotation package for GO
enrichment analysis using GOstats. The GO annotation is from
InterProScan. I plan to create a data frame with three columns: probeid,
geneid and GO, then build the annotation package. Any suggestions?

Thanks,
Xinxia
