Dear list, I've tried to use the nsFilter function from genefilter package to perform nonspecific filtering on a Human Gene ST 1.0 dataset. The expression set has the hugene10sttranscriptcluster.db annotation package, but when nsFilter is applied: nsFilter(subEset,var.cutoff=0.5) # Removes AFFX genes, those without EntrezGene IDs, etc Error is do.call(paste(chip, "_dbconn", sep = ""), list()) : "hugene10sttranscriptcluster.db_dbconn" cannot be found Maybe nsFilter is not built for this kind of microarrays, although varFilter,from the same package, works, because it makes use of the expression values only. I've made some search on Google, but no success. I can write a function that removes the different control genes in Human Gene (AFFX, spike, neg_control,pos_control,etc) and those without EntrezGene ID, but wanted to know if there is a function that handle this for this kind of microarrays. Thanks, Javier sessionInfo() R version 2.10.0 (2009-10-26) i386-pc-mingw32 locale: [1] LC_COLLATE=Spanish_Spain.1252 LC_CTYPE=Spanish_Spain.1252 [3] LC_MONETARY=Spanish_Spain.1252 LC_NUMERIC=C [5] LC_TIME=Spanish_Spain.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] Matrix_0.999375-31 lattice_0.17-26 [3] ALL_1.4.7 genefilter_1.28.0 [5] pd.hugene.1.0.st.v1_3.0.0 Category_2.12.0 [7] KEGG.db_2.3.5 hugene10sttranscriptcluster.db_4.0.1 [9] org.Hs.eg.db_2.3.6 RSQLite_0.7-3 [11] DBI_0.2-4 oligo_1.10.0 [13] preprocessCore_1.8.0 oligoClasses_1.8.0 [15] GSEABase_1.8.0 graph_1.24.0 [17] annotate_1.24.0 AnnotationDbi_1.8.0 [19] Biobase_2.6.0 loaded via a namespace (and not attached): [1] affxparser_1.18.0 affyio_1.14.0 Biostrings_2.14.0 grid_2.10.0 [5] IRanges_1.4.0 RBGL_1.20.0 splines_2.10.0 survival_2.35-7 [9] tools_2.10.0 XML_2.6-0 xtable_1.5-5 >

Thanks for this. As Robert mentions, the intention is that nsFilter should work whether or not the '.db' extension is present. Changes in the last development cycle introduced bugs where this was not the case. 1.28.1 addressed this in one location, this is a second; version 1.28.2 should fix this when it becomes available, probably after noon (Seattle time) tomorrow.

This is possibly due to my email about one week ago when I suggested that: annotation(OligoEset) <- "hugene10sttranscriptcluster.db" would suffice.

But apparently the ".db" bit isn't required. it should not be. It is essentially conveying an implementation detail (that this annotation package is stored as a database), clearly other implementations (like our old environment based one should also work, if one wanted to use them). So my preference is that the .db not be required. best wishes Robert > > b > > On Nov 27, 2009, at 1:51 PM, Javier P?rez Florido wrote: > >> Martin Morgan escribi?: >>> Javier P?rez Florido wrote: >>> >>>> Martin Morgan escribi?: >>>> >>>>> "James W.

Dear Javier, It might be of interest to you that package xps could handle your problem of removing different control genes, since function rma() has a parameter "exonlevel" for HuGene and HuExon arrays, which allows you to define which probesets to use for rma, e.g. exonlevel="affx+core" will use only probesets of category 'unique', 'similar' and 'mixed' plus the standard AFFX controls, while exonlevel="metacore" will only use probesets of category 'unique', see the help "?exonLevel". Thus there is no need to remove these probesets afterwards. Furthermore, xps has also different methods for non-specific filtering, see help "?PreFilter" Best regards Christian _._._._._._._._._._._._._._._._._._ C.h.r.i.s.t.i.a.n S.t.r.a.t.o.w.a V.i.e.n.n.a A.u.s.t.r.i.a e.m.a.i.l: cstrato at aon.at _._._._._._._._._._._._._._._._._._ Javier P?rez Florido wrote: > Martin Morgan escribi?: >> "James W.
