construct gene expression matrix

Postby dabd » Nov 04 2009 11:17 am

Hi,

I would like to construct a final gene expression matrix (genes x conditions) from this experiment http://www.ebi.ac.uk/microarray-as/ae/files/E-SMDB-1886
Looking at the processed data file it is not clear for me which of the following columns I should use to construct the matrix:
SMD:RESULT.CH2BN_MEDIAN »
SMD:RESULT.CH2DN_MEAN »
SMD:RESULT.CH2IN_MEAN »
SMD:RESULT.LOG_RAT2N_MEAN »
SMD:RESULT.RAT1N_MEAN »
SMD:RESULT.RAT2N_MEAN »

These columns are described here http://www.ebi.ac.uk/microarray-as/aer/ ... =827368937

Thanks.
