Hello List

I have a set of Rat Gene ST CEL files to analyse and have started looking into using xps for this. I have begun by building the required scheme file for the arrays. I have downloaded the relevant files from affymetrix (RaGene-1_0-st-v1.r4.clf,  RaGene-1_0-st-v1.r4.pgf, RaGene-1_0-st-v1.na32.rn4.probeset.csv & RaGene-1_0-st-v1.na32.rn4.transcript.csv) and built the scheme file as follows:

libdir <- paste(getwd(), 'xpsAnalysis/annotationFiles', sep='/') # the annotation files are here

xps.scheme <- import.exon.scheme('Scheme_RaGene10stv1r4', filedir=paste(getwd(), 'xpsAnalysis/rootScheme', sep='/'), layoutfile = paste(libdir,'RaGene-1_0-st-v1.r4.clf', sep='/'), schemefile = paste(libdir,'RaGene-1_0-st-v1.r4.pgf',sep='/'), probeset = paste(libdir,'RaGene-1_0-st-v1.na32.rn4.probeset.csv', sep='/'), transcript = paste(libdir, 'RaGene-1_0-st-v1.na32.rn4.transcript.csv', sep='/')) # create the scheme


Note that I use the import.exon.scheme command as per advice from cstrato for the r4 annotation files (some weblink I can't find just now).


This goes well and I get a .root file in the right directory. However I noticed that during the process the following warning is issued:

Importing </.../xpsAnalysis/annotationFiles/RaGene-1_0-st-v1.na32.rn4.probeset.csv> as <RaGene-1_0-st-v1.anp>...
Note: The following header columns are missing or in wrong order: 
   <mouse_fl>
   <mouse_mrna>
   <rat_fl>
   <rat_mrna>


Something to be concerned about?

I'm not sure what the mouse data would be doing in the annotations for the rat chips but I'm not yet familiar with the platform.

Advice appreciated.

Thanks
