Hi, All,
 
I want to transform Affymetrix MAS expression values (above 20,000) into log(base 2) values with header(arry1, array2, array3...) and gene names(gene1, gene2, gene3...) intact. Transformation of log(base 2) one column one time in Excel is laborious, albeit well done.
Anyone have the experience?
Any advice and suggestions will be much appreciated.
Many thanks in adavance.

Best Regards
