Microarray data processing summary.

Summary of microarray data processing detailing the number of genes passing the different filters and analyses carried out. The first column indicates the preprocessing method employed. The second column (IQR>0.5) indicates the number of probesets with interquartilic range over 0.5, except in the MAS5 analysis where all probesets were included. The third column indicates the comparisons that were carried out (FRNT corresponds to frontal skin, MSCH to mesenchyme, and PED, to pedicle skin). P<0.05 indicates the number of probesets with significant expression changes according to a paired t-test. Adj p<0.05 represents the number of significant comparisons alter False Discovery Rate correction for multiple tests. GO:CC y GO:BP correspond to the number of genes with significant gene expression changes (without correction) that were included in any of the Cellular Components (GO:CC) or Biological Processes (GO:BP) lists according to the Gene Ontology terms. The last column, bibliography, details the number of genes that fulfilled all previous conditions and were more likely involved in relevant processes according to published references and the OMIM database. Last file algorithms, MAS5 P/M/A, corresponds to the probesets classified by MAS5 algorithms as present or marginal in at least 2 or the 3 samples of velvet.
