Correlation between structural genomic parameters and both gene expression and expression.

Data are presented both for oligo-array and MPSS assays. Statistical significances: ns = not significant; §P<0.05 †P<0.01; ‡P<0.001;*P<0.0001. Sample size of the correlations were comprised between n = 12051 and n = 14236. Note1. For this calculations, gene for which expression was zero were not considered to avoid potential problem arising from defective probes (Eisenberg and Levanon, 2003). Note2. For introns parameters, data are presented both considering and excluding (w0) genes without introns.
