Are genes changing expression in other studies consistantly up- or down-regulated in your experiment ?

To compare the results of a genome-wide differential gene expression analysis to experiments in the reference database, please provide two data columns: the gene identifiers and the associated differential expression scores.
gCMAPWeb will use the JG statistic (Jiang & Gentleman, Bioinformatics, 2007), a summarized t-statistic, to identify experiments with correlated or anti-correlated expression changes.
Choose this option e.g. to analyze

- z-scores obtained from comparing treated vs. control samples

Please note: to calculate the JG statistic, please provide scores that are centered on zero and (at least approximately) follow a normal distribution, e.g. z-scores, t-statistic, etc.
