Hi,

I just tried affxparser on an example CEL file from the new Affymetrix

Command Console software.

 

> library(affxparser)

> convertCel("agcc.cel","gcos.cel")

Error in sprintf("DatHeader=%s\n", datHeader) : zero-length argument

 

> createCel("test.cel",header=readCelHeader("agcc.cel"))

Error in sprintf("DatHeader=%s\n", datHeader) : zero-length argument

 

So the error seems to happen at the createCell stage already.

Reading the cel file with readCel does work!

I have R 2.6.0/BioC 2.1 and affxparser version 1.10.0.

Chip type is RAT_230 (I can provide the cel file if someone is

interested). 

 

Any ideas how to solve this? (As an alternative - it would be fully

sufficient for me to use readCel if there was a method to get the

output into an AffyBatch object.)

 

Regards,

Guido
