Dear Christian,

I am new to XPS and following your paper on using XPS for my Gene St array (HuGene-2_0-st design). I need the degradation plot.

I used the listed code to create scheme object:

> scmdir <- "D:/GeneST_Analyse/CELFiles/schemes"
> libdir <- "D:/GeneST_Analyse/CELFiles/libraryfiles"
> anndir <- "D:/GeneST_Analyse/CELFiles/Annotation"
> scheme.hugene20stv1.na35 <- import.exon.scheme("Scheme_HuGene20stv1_na35",filedir=scmdir,layoutfile=paste(libdir,"HuGene-2_0-st.clf",sep="/"),schemefile=paste(libdir,"HuGene-2_0-st.pgf",sep="/"),probeset=paste(anndir,"HuGene-2_0-st-v1.na35.hg19.probeset.csv",sep="/"),transcript=paste(anndir,"HuGene-2_0-st-v1.na35.hg19.transcript.csv",sep="/"))

I got the following error. Could you please give me any suggestion?

Error Message:

Error in import.exon.scheme("Scheme_HuGene20stv1_na35", filedir = scmdir, :
error in function ‘ImportExonSchemes’

Thanks in Advance

Dear Venkatesh,

Could you please answer the following questions:
- sessionInfo()
- which version of Windows do you use?
- how do you run R?

Please try the following to run on the Windows Console, i.e. RTerm with 'verbose=TRUE',
and send me the complete output from the Console:

scheme.hugene20stv1.na35 <- import.exon.scheme("Scheme_HuGene20stv1_na35",filedir=scmdir,
layoutfile=file.path(libdir,"HuGene-2_0-st.clf"),
schemefile=file.path(libdir,"HuGene-2_0-st.pgf"),
probeset=file.path(anndir,"HuGene-2_0-st-v1.na35.hg19.probeset.csv"),
transcript=file.path(anndir,"HuGene-2_0-st-v1.na35.hg19.transcript.csv"),
verbose=TRUE)

Note: On Windows you will see the verbose messages only when starting R from the command line,
i.e. using RTerm.

Regards,
Christian

Hi Christian,

Thanks for the reply. I tried running on windows console i.e. RTerm.

Hi Christian,

For RNA degradation plot I am getting an error. Please check the following:

load existing ROOT scheme file and ROOT data file

scheme.exon <- root.scheme(paste(scmdir,"Scheme_HuGene20stv1_na35.root",sep="/"))
data.exon <- root.data(scheme.exon, paste("D:/GeneST_Analyse/CELFiles/rootdata/tmp_data_exon_cel.root",sep="/"))

qualification - rlm

rlm.all <- rmaPLM(data.exon, "tmp_exonRLMall", filedir=getwd(), tmpdir="", qualopt="all", option="transcript", exonlevel="affx+core", add.data=FALSE)

(or)

rlm.all <- fitRLM(data.exon,"tmp_exonRLM", qualopt="all", option="transcript", exonlevel="affx+core", verbose=FALSE)

And I get the following error:
