| Description |
Whole transcriptome expression analysis of INA6 cells on Affymetrix Human Tiling 1.0 array set. IL-6 has been withdrawn for 13 hours which initiates apoptosis. Expression data was processed with our permutation approach (TileShuffle).
|
| Data processing |
Affymetrix Human Tiling 1.0 probes were mapped to human genome assembly hg18 using the corresponding BPMAP files. The expression data were processed with our new permutation approach TileShuffle. TileShuffle was applied using only perfect match (PM) probes, a window size of 200, the arithmetic mean trimmed by maximal and minimal value as scoring function, three GC content bins, 10000 permutations, and a q-value threshold of 0.05. In order to estimate the significance of a window score we repeatedly permute all probe intensities across the array while interchanging only those that belong to the same sequence-specific affinity bin, recompute the window scores, and compare them with the original ones. By counting the number of permuted windows with higher score, we estimate empirical p-values of windows, and report q-values adjusted according to Benjamini and Hochberg ("Controlling the False Discovery Rate: A Practical and Powerful Approach to Multiple Testing". Journal of the Royal Statistical Society. Series B (Methodological), 57:289-300, 1995.).
