[BiO BB] question about Agilent microarray data format

[James Anderson]

Hi, 
  I have some Agilent microarray data. I am not familiar with the format. (I am more familiar with Affy data). There are some columns named "gProcessedSignal" "rProcessedSignal", "LogRatio", etc. I guess it's more like cDNA with two channels. So should I use the LogRatio value to perform the next step analysis (gene selection, PCA, clustering, etc).  

  Thanks,
  James
