bioinformatics - CEL files processing: are all cel files raw data? -

using affymetrix data, have thought "cel files" represent raw info need processed (normalized example) before beingness used.

nevertheless on geo omnibus web site, when @ cel files studies (not all: please @ illustration link: http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=gsm467778),

you can read values of gsm467778_50.cel correspond to: "rma normalised signal intensities" (in illustration above) not phone call "raw values".

therefore don't know if in example, should normalize cel files or if done ?
