Dear Dr. Diez,

I am trying to use codelink package to do analysis with Codelink arrays. It is indicated that codelink package only recognizes the text files exported from the Codelink software. We have 32 txt files, when I used :
files<-list.files(pattern="txt")
data<-readCodelink(files=files)

it returns:

Error in readHeader(files[n], dec = TRUE) : Not a Codelink exported file.

The first several rows of files are:

PROJECT
EXPERIMENT
SAMPLE  Sample001
DATE    2007-10-26T17:19:48


GENEID  NCBI_ACCESSION  TYPE_FLAG       LO_ARRAY_ID     EXPRESSIONVALUE NORMALIZEDEXPRESSIONVALUE       GENESPRINGFLAG  CODELINKFLAG    SPOT_COL        SPOT_ROW        SPOTMEAN        SPOTMEDIAN      BKGMEAN BKGMEDIAN
.......


I emailed to the person from the company. They claimed that this txt file is from Codelink system directly without any manipulation. I checked the code of readCodelink, it seems there should be product, number of genes..... fields. Would you like to help me about this? Will the file needs more header to be recognized by the codelink package?

Thanks a lot,
Lixia
