Heat map of the number of common genes or function terms between signatures. a A common gene matrix of 33 signatures by 33 signatures was shown by colour code. The two signatures share at least three common genes (red); the two signatures share one or two common genes (grey); the two signatures share none common genes (green). b A common function terms matrix of 29 signatures by 29 signatures was shown by colour code. Four out of the total 33 signatures did not have enriched significant function terms. The two signatures share at least three common terms (red); the two signatures share one or two common terms (grey); the two signatures share none common terms (green)
