Hi all. This may in fact actually not be a problem, it may be something silly that I'm doing. But, something strikes me as odd. Below is my explanation. I am working with the Affymetrix promoter tiling arrays. My starting point is a BPMAP file, which you can get from Affy library bundle at: http://www.affymetrix.com/products/arrays/specific/human_promoter.affx ... or I have also been using the re-worked BPMAP file you can get from the people who developed MAT: http://chip.dfci.harvard.edu/~wli/MAT/Download.htm So, I use 'makePDPackage' to create a R package, along the lines of: (I've just renamed the downloaded BPMAP file to have 'affy' or 'harvard' in the name of the file, so that I can remember how to tell them apart) > makePDpackage ("Hs_PromPR_v02 -3_NCBIv36 .affy.bpmap",type="tiling",manufacturer="affymetrix",genome="hg18") affymetrix tiling The package will be called pd.hs.prompr.v02.3.ncbiv36.affy Array identified as having 914 rows and 914 columns. Creating package in /export/share/disk501/lab0605/mrobinson/projects/ microarray/pd.hs.prompr.v02.3.ncbiv36.affy > makePDpackage ("Hs_PromPR_v01 -3_NCBIv36 .NR .harvard.bpmap",type="tiling",manufacturer="affymetrix",genome="hg18") affymetrix tiling The package will be called pd.hs.prompr.v01.3.ncbiv36.nr.harvard Array identified as having 914 rows and 914 columns. Creating package in /export/share/disk501/lab0605/mrobinson/projects/ microarray/pd.hs.prompr.v01.3.ncbiv36.nr.harvard ... then do R CMD INSTALL ... from the command prompt. One thing that strikes me as odd is the fact that it recognizes it as having 914 rows and columns. See below. So, I read in the data for a single file and look at the raw data for a particular X and Y location on the chip. And compare this to what I get from 'readCel' in the affxparser package. > rd<-read.celfiles("CEL/ test1.CEL",pkgname="pd.hs.prompr.v01.3.ncbiv36.nr.harvard") Platform design info loaded. The intensity matrix will require 35.79 MB of RAM. > pd<-getPD(rd) > length(pd$X) [1] 4286817 > dim(rd) Features Samples 4286817 1 > w<-which(pd$X==1344 & pd$Y==854) > w [1] 1267129 > exprs(rd)[w,] [1] 123 > library(affxparser) > x<-readCel("CEL/test1.CEL",readXY=TRUE) > x$header[c("rows","cols")] $rows [1] 2166 $cols [1] 2166 > w<-which(x$x==1344 & x$y==854) > w [1] 1851109 > x$intensities[w] [1] 8074 So, this chip does have 2166 rows and columns, which could be introducing problems in the indexing. I haven't dug any deeper on this. Anyone know what is happening? Is this a problem in making the package through 'makePDPackage', or do I misunderstand the correspondence between the elements of a 'TilingFeatureSet' and the corresponding 'platformDesign' object?

Thanks again Benilton. Is there something about the BPMAP files for the Promoter Tiling array? I read these files regularly using 'readBpmap' from the affxparser package. See below. With pdInfoBuilder, I get an error of the sort: ------- Unable to read file: Hs_PromPR_v02-3_NCBIv36.affy.bpmap, is it a BPMAP file? ------- Unable to read file: Hs_PromPR_v01-3_NCBIv36.NR.harvard.bpmap, is it a BPMAP file? ------- (I've installed pdInfoBuilder v1.5.1 (i.e. BioC 2.3) onto R 2.7.1, since I don't have easy access to 2.8 ... though from the error message below, it appears that its the BPMAP file) I've posted the BPMAP/CIF files I am using at: http://bioinf.wehi.edu.au/folders/mrobinson/BPMAP/ Cheers, Mark > library(pdInfoBuilder) Loading required package: Biobase Loading required package: tools Welcome to Bioconductor Vignettes contain introductory material.
