Hello, Sorry to disturb. I am studying gene expression in mouse and today I downloaded "GnfMouseAtlas2median" file from table browser. By reading previous threads, I found the last column is the so-called average difference value from affymetrix. I want to find out whether several genes express in cortex or not. Then which value should I use as the cutoff to distinguish "expressing in cortex" and "not expressing in cortex" ?
One previous thread also mentioned average difference value could be negative values. But in this file, it seemed that all average difference values are positive. Could you tell me the reason? Thank you! Best regards, Xinwei Han _______________________________________________ Genome maillist - [email protected] http://www.soe.ucsc.edu/mailman/listinfo/genome
