Palindromes, homopolymers and simple repeats .

Description

This series contains features that are directly computed from the genome sequence with ad hoc scripts, including short palindromes, homopolymers and simple repeats. Some of these features appear to be enriched or depleted in certains regions. For instance, palindromes are enriched in the regulatory regions of certain species. Simple repeats tend to be depleted in conserved non-coding regions.
