freshVsFrozen: Reproducibility between Fresh and Frozen B-cell subtypes

Description

This dataset contains a data.frame of \(t\)-scores (from a Linear mixed effects model) and \(p\)-values for differential expression between pre (Im, N) and post germinal (M, PB) centre cells within peripheral blood. The first and second column contain the the test for the hypothesis of no differentially expression between pre and post germinal cells for the freshly sorted and gene profiled cells. The third and fourth column contain the the test for the hypothesis of no differentially expression between pre and post germinal cells for the cryopreserved (frozen), thawed, sorted, and gene profiled cells. The fifth and sixth column contain the the test for the hypothesis of no differentially expression between fresh and frozen cells. The used array type was Affymetrix Human Exon 1.0 ST microarray.

Format

The format of the data.frame is:

'data.frame': 18708 obs. of 6 variables: $ PreVsPost.Fresh.tstat : num -1.073 -0.381 -1.105 -0.559 -1.054 ... $ PreVsPost.Fresh.pval : num 0.283 0.703 0.269 0.576 0.292 ... $ PreVsPost.Frozen.tstat: num -0.245 -0.731 -0.828 -0.568 -1.083 ... $ PreVsPost.Frozen.pval : num 0.806 0.465 0.408 0.57 0.279 ... $ FreshVsFrozen.tstat : num 0.836 1.135 -0.221 0.191 -0.783 ... $ FreshVsFrozen.pval : num 0.403 0.256 0.825 0.849 0.434 ...
