| Description |
Whole transcriptome expression analysis of colorectal carcinoma cells with defunct P53 on Affymetrix Human Tiling 1.0 array set. Intensities were processed with TileShuffle.
|
| Data processing |
Affymetrix Human Tiling 1.0 probes were mapped to human genome assembly hg18 using the corresponding BPMAP files. Intensities of perfect match (PM) probes were processed with TileShuffle (Otto C, Reiche K, Hackermüller J. "Detection of differentially expressed segments in tiling array data". Bioinformatics. 2012 Jun 1;28(11):1471-9. Epub 2012 Apr 6.) using a window size of 200, the arithmetic mean trimmed by maximal and minimal value as scoring function, four 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.).
