[BioC] marray or rma?

[James MacDonald]

The marray* packages are for spotted cDNA arrays, and rma, which is part
of the affy package is for Affymetrix oligonucleotide microarrays.
Either package can be used for calculating normalized expression values,
but only for a particular microarray type.

Hi,
I don't know the difference between the use of the 'marray' package and
the use
of the function 'rma'. I would like to calculate the expression from raw
data
and to normalize all the data afterward.
Thanks for your help,
Jamila
