how to use SAM (Significance Analysis of Microarrays) for .cel files??

Question

[sumitha.saseendran]

how do i input SAM with .cel files, now that it is integrated into R? In the manual it is stated that the input file should be in a particular table format, but all the GEO data series that i have, have the raw data in cel file format. I'm new to R and microarray analysis and have no idea how to go about it. Please help!!!

You can use the oligo Bioconductor package to load and normalize data from .CEL files.
